Your data center migration plan guide: Step-by-step checklist

Data center migration is a complex process, but one that is often inevitable for many businesses. The complex series of tasks involved in moving information, applications, and infrastructure from one data center environment to another requires meticulous planning and execution to ensure minimal disruption to business operations.

Whether you’re moving to a new site or transitioning to a cloud environment, Evernex’s step-by-step guide to creating a data center migration plan will help you through each stage of the process, from planning to post-migration optimization. We’ve even provided an easy-to-use checklist to help you make sure no step gets forgotten! 

What is a data center migration?

Data center migration is the process of moving IT hardware, software and data from one data center environment to another.

An enterprise data center comprises multiple different elements, both physical and virtual. These include servers, networking equipment, storage devices, operating systems, and security measures. The more elements your data center infrastructure has, the more complicated it will be to migrate it all efficiently.

 

Why do businesses need a data center migration plan?

Companies can decide to perform a data center migration for several reasons. Such motivations may include:

• Upgrading hardware and software to keep up with evolving business needs, including the transition to modern architectures such as converged infrastructure or HCI.
• Equipment reaching its End of Life (EOL) or End of Support (EOS) dates, prompting infrastructure refreshes or the switch to supported environments.
• The business changing location or facility.
• Scaling or virtualization of business operations.
• Consolidating multiple data centers into one centralized environment.
• Compliance with new regulatory requirements or standards.

One of the most important reasons a plan is so vital here is the protection of a company’s data. The information contained in a business IT infrastructure can be both sensitive and crucial to operations. As a result, keeping it secure through the migration process is essential to avoiding both data loss and the risk of information falling into the wrong hands.

A data center migration checklist is not just useful, but pivotal to making the transition secure, efficient and compliant.

 

What are the key aspects of a migration project?

A data center migration can be broken down into several key aspects. Here are the main factors to bear in mind when planning a data center migration:

Factor	What to consider
Infrastructure assessment	Evaluate the current data center system. This includes hardware, software, and applications.
Data center requirements	Define the requirements for the new data center. This should cover capacity, performance, security, connectivity, and location. What will you need to successfully deploy and manage your new infrastructure?
Budgeting	Establish a budget that covers all aspects of the migration, from equipment costs to labor.
Timeline	Develop a realistic timeline that accounts for potential delays. Bear in mind the amount of time your business can tolerate downtime and stalls in operations.
Risk management	Identify potential threats and create strategies for risk avoidance and disaster recovery. You can check out our data center recovery checklist for more information
Stakeholder communication	Ensure transparent and comprehensive communication with stakeholders throughout the process.
Resource allocation	Assign clearly defined roles and responsibilities to team members. What tools and skills will you need to execute the migration securely and efficiently?

Physical relocation or cloud migration?

A data center migration can be physical, virtual, or hybrid.

• A traditional migration, or relocation, is the movement of a data center infrastructure to a second, on-premises site. This offers enhanced control and security measures in comparison to server virtualization.
• A cloud migration moves an IT system from an on-premises environment to a virtual, cloud-based environment. This reduces the need for physical hardware, minimizing the organization’s spatial footprint. It also enables more efficient scaling, management, and centralization of IT resources.
• A hybrid migration combines elements of cloud and on-premises data centers. This allows businesses to choose the most adequate aspects of both migration strategies and create an infrastructure fully adapted to their operations.

Is there a difference between a data center migration and a relocation?

While the two terms are often used interchangeably, they do not refer to exactly the same process. A data center relocation project most commonly refers to the movement of physical data center hardware from one place to another. Meanwhile, a migration is broader in scope. It can include relocating physical infrastructure, but may also involve moving workloads, applications, or data between environments. Data center migration also encompasses shifts between physical spaces and virtualized ones, such as the cloud.

Your step-by-step data center migration checklist

A thorough, well-organized checklist is essential for a successful data center migration project. With this list, we help you cover the migration process end to end, from planning to testing.

Pre-migration steps

1.Define the scope and objectives of the migration plan
Begin by clearly outlining the scope of the data center migration project. Determine which systems, applications, and data you need to move and set specific, measurable objectives for the migration.

2.Identify and prioritize the workloads to migrate
Assess which workloads to migrate and in which order. Prioritize based on importance, complexity, and dependencies.

3.Develop a data center migration project plan and timeline
Create a detailed, practical project plan that covers all tasks, logistics, and deadlines. This includes arranging the secure packaging and transport of hardware, preparing for downtime, data migration methods, and potential risks and setbacks.

4.Establish a communication plan
Develop a comprehensive communication plan to keep all stakeholders informed about the migration’s progress. Such a plan should outline the frequency, methods, and key points of contact.

5.Inventory audit
Document all assets, including hardware, applications, and data. This task includes identifying any undocumented devices and confirming who each asset belongs to. Additionally, it should cover what services the asset performs, its criticality in the infrastructure, and its EOL/EOSL dates.

6.Compatibility checks
Ensure compatibility between old and new environments to ensure smooth, efficient performance after the move.

7.Back up Data
Perform comprehensive backups to prevent data loss in case of any issues. Using Back-up-as-a-Service (BaaS) is particularly helpful in this stage, ensuring the availability and security of enterprise data by maintaining virtualized, offsite copies.

Offline, airgap storage solutions such as tape libraries are also highly effective for secure data backup.

8.Choose a migration strategy
Choose between a phased approach, big bang, swing or hybrid strategy.

• Phased migration = Gradually transitioning your data or apps in steps.
• Big bang = Migrating the entire IT system all at once, also known as “lift-and-shift”.
• Hybrid strategy = Old and new systems run simultaneously, combining the speed of big bang with the continued system availability of phased migration.
• Swing move= A staged approach where systems are temporarily moved to an interim environment while infrastructure is transferred to its final destination.

9.Test plan
Create a detailed testing plan to validate the migration process. At a minimum, this will cover:

• Compatibility
• Reliability and performance
• Data security and accessibility
• Network connectivity

Migration execution

10. Execution
Follow the migration plan. This involves the shutting down, packaging and relocation of IT hardware, shifting data and software applications, and setting everything up in the new environment as per the strategy.

11. Monitoring
Continuously monitor the migration process for issues and address them promptly. You can use performance metrics, such as PUE and latency, to monitor the functionality of the migrated workloads. This also helps to identify and resolve any issues.

12. Testing
Conduct the planned tests to ensure data integrity and system functionality in the new environment. This includes performance testing, failover testing, and application testing to ensure that everything works correctly in the new environment.

Post migration steps

13. Validation
Ensure that all systems, applications, and security measures are functioning correctly. Does the migrated infrastructure meet your enterprise needs?

14. Optimization
Fine-tune the new environment for performance and efficiency. This can include software patches, reconfigurations, resource rightsizing, and implementing updated security or monitoring practices.

15. Review and update documentation
Ensure all documentation is up to date and reflects the new data center infrastructure. This should include network diagrams, system configurations, runbooks, and updated DNS configurations.

16. Training
Provide training for staff on the new systems and processes to reduce any risk of human error later.

17. Support
Establish a comprehensive support plan to address any post-migration issues. This can be internal or leverage third-party maintenance services, such as those provided by Evernex.

18. Data center decommissioning
Decommission legacy infrastructure according to an predefined plan once migration is complete. Properly executed decommissioning includes ensuring that:

• data is securely erased
• obsolete assets are correctly disposed of or repurposed
• all dependencies have been fully transitioned without disrupting operations

What are best practices for migrating a data center?

Best practices are guidelines which help enterprises maintain efficiency, security and compliance, adhering to industry standards.
The following practices can help ensure a successful data center migration and reduce downtime:

• Clarifying the purpose of the data center migration

Clearly defining the objectives of the migration, whether this be cost reduction, scaling, or virtualization, ensures all stakeholders are aligned. This clarity guides decision-making, prioritization, and success metrics throughout the project.

• Appoint a qualified migration lead

Designating a single, experienced leader to oversee the migration helps streamline decision-making, maintain accountability, and avoid delays caused by complex approval chains.

• Planning

A thorough planning phase will help prevent costly disruptions and ensures a smoother transition.

• Testing

Validating the new data center infrastructure in advance ensures it performs as required and can support the necessary workloads.

• Using a phased approach

Migrating workloads in stages can help minimize disruption and risk, allowing issues to be identified and resolved incrementally. Starting with less critical workloads is often recommended.

To keep disruption to a minimum, organizations will benefit from keeping in mind four main principles: thorough planning, clear communications, prioritization, and well-defined roles and leadership.

Can I migrate hardware past its EOL or EOS date?

In principle, it is absolutely possible to migrate IT equipment that has reached its End of Life (EOL) or End of Support (EOS) date, especially if that equipment is well-maintained through consistent third-party support. However, doing so can introduce certain risks, including:

• Reduced reliability
• compatibility limitations
• increased security vulnerabilities
• compliance issues in certain sectors

Because EOS hardware is no longer supported by the original manufacturer, businesses must carefully assess whether maintaining the existing hardware remains cost-effective and operationally viable. While its lifecycle can be extended through Third-Party Maintenance, many businesses use migration projects as an opportunity refresh legacy devices or simply consolidate the workloads onto more efficiently configured equipment. This has the benefit of reducing the data center’s overall footprint.

A professional migration team can help advise on the best options regarding your EOL/EOS equipment during migration.

How can I refresh my EOL hardware during a migration?

If you do choose to use your data center migration process as an opportunity to refresh your post-EOL or EOSL hardware, it is worth bearing in mind a few pointers:

Advice	Explanation
Prioritize critical systems	To control costs, organizations often combine selective hardware refreshes with Third-Party Maintenance (TPM), prioritizing upgrades only for the most business-critical, performance-limiting, or unsupported assets.
Review future scalability requirements	Ensure your new infrastructure is aligned with future business needs. Choosing equipment that supports virtualization, hybrid environments, or increased workloads can help avoid further refresh cycles in the near future.
Consider refurbished	Investing in certified refurbished devices to replace your retired assets can also reduce the total cost of the refresh process, while maintaining security and performance.
Proper data disposal and compliance	Any retired hardware should undergo securely data wiping and IT recycling, refurbishment, or disposal in line with local regulations and industry standards.

Phasing your refreshes and reviewing your scalability needs will help create a more agile and resilient IT environment without requiring a complete infrastructure overhaul. Meanwhile, secure ITAD for retired hardware minimizes security and compliance risks.

What are the main challenges of a data center migration project?

The data center migration process can pose several important risks and difficulties, especially if not well planned or executed. Here’s a quick list of the main challenges a data center relocation can face, and how to mitigate them. For more information, you can also check out our blog post on how to overcome data center migration challenges.

Extended downtime

Downtime can be disastrous for enterprises of all sizes. It can bring productivity to a halt and cause significant damage to revenue. The longer downtime continues, the bigger the impact on operations and income.

How to avoid it:
Minimizing downtime through careful planning, risk mitigation and efficient execution is crucial to avoid business disruption. Before the migration process begins, businesses should identify critical systems, dependencies and acceptable downtime windows. They can then build a migration plan prioritizing continuity.

Moving workloads and infrastructure in controlled stages through phased migration also allows operations to continue for as long as possible and limits the impact of unexpected issues, reducing overall downtime. Where possible, migrations should also be scheduled during low-traffic periods to minimize operational disruption.

Unrealistic expectations

Data center migrations cost time, effort and capital. Unrealistic expectations with regard to these factors can cause confusion, internal and external conflicts, and budget problems.

How to avoid it:
Establishing a complete plan, accounting for every device, replacement, upgrade, and possible delay is key to managing expectations. Transparent communication and clear division of responsibilities is also essential for avoiding problems with stakeholders and between departments.

Data integrity

Ensuring the accurate, secure and complete transfer of data is fundamental to any data center migration strategy. Loss, corruption, or inconsistencies can lead to faulty analytics, broken applications, or compliance issues. Even small discrepancies can cascade into major operational problems.

How to avoid it:
Robust validation processes and backup strategies ensure the data is accurately transferred and fully intact before systems go live in the new environment. Tested recovery strategies should also be in place to get systems and data back online in case of unexpected disruption.

Incompatibility between devices and systems

Legacy hardware, outdated software, and differing configurations can cause incompatibility issues. These mismatches can prevent applications from running correctly. This can also delay the transition or require expensive redesigns.
How to avoid it:
Thorough compatibility assessments in advance facilitate a smooth transition and reliable performance at the other end.

Security

Data in transit may be vulnerable to exposure and unauthorized access. Migrations can also open temporary security gaps that attackers could exploit, while misconfigurations can create long-term risks.

How to avoid it:
Strong encryption, strict access controls, and validated security configurations in the destination environment are critical to maintaining end-to-end protection.

Complexity

Data center migrations involve multiple interconnected systems and applications. Even a small oversight can ripple across applications and services, leading to unexpected
failures or delays.

How to avoid it:
Clear communication, detailed runbooks and mapping, and phased migration strategies can allow teams to manage this complexity and gain full IT visibility.

Lack of prioritization

Failure to correctly prioritize workloads can lead to performance bottlenecks and operational disruption.
Migrating systems without assessing their business importance, dependencies or performance requirements may also increase the risk of delays and resource inefficiencies.

How to avoid it:

Businesses should classify workloads according to their criticality, operational impact and technical dependencies, prioritizing mission-critical applications and services for careful planning, back-up, testing and support. Detailed migration roadmaps can help companies sequence their workloads to reduce operational risk and ensure resources are allocated where they are needed most.
Generally, low-risk or non-critical workloads should be migrated first, followed by independent applications (those with fewer dependencies), and then the high-impact loads.
