How to Anticipate and Overcome Problems in Your Data Center Migration
There are many situations
Whatever your reason, a data center migration is one of the most complex IT jobs that you can take on. You want to execute a smooth migration, with maximum speed and minimal trouble, while minimizing the risks of unexpected downtime and interruption to your company’s revenue.
We have two words for you: “Plan Well!”
The key to
If possible, start planning for a data center migration at least six months in advance. This gives you plenty of time to get organized, do the prep work, and map out the migration. It also gives you time to anticipate problems and work out solutions
First, take a comprehensive inventory of all servers and equipment that will be moved to the new data center and determine if any equipment has reached
As part of your inventory, document the following:
Impacts – What will be the impacts of downtime during a physical IT migration? If, for example, a server is disconnected and an eCommerce application is offline for 24 hours, what impact will that have on your business?
Interdependencies – What are the upstream and downstream interdependencies of each device in your IT ecosystem? If you shut off a server that hosts virtual desktops, for example, what will be the impact on employees (upstream) who use those desktops, or on storage units (downstream) that receive replicated backup data from that server?
Storage Units – If a storage reconfiguration is planned as part of the migration, make sure that any new storage units you buy will be compatible with your old storage units.
Documentation – If they don’t already exist, you’ll need to develop full rack elevation and port/cable map documents for both the current and future locations.
Identify the Key Players and Objectives
Next, identify the people or departments who will be involved in the data center migration, and what responsibilities each will have. List and document the following
Stakeholders – The people affected by relocation, need to be consulted about migration activities, application downtime priorities, and organizational impacts
Also, document any department- or group-specific requirements, as well as the overall business drivers, timelines, and objectives you wish to achieve.
Develop a Comprehensive Project Plan
Then, construct a detailed plan for the data center relocation that includes the following elements:
*A project charter identifying stakeholders, objectives, budgets, and priorities
*A project plan with tasks and resource assignments for each person or group.
*A risk management plan to document risks and contingencies.
*Checklists and sign-off sheets for each involved party.
*A timeline and schedule of key events in the migration.
*Budget components that you can use to justify budgets.
*An end-to-end test plan for each group.
Brainstorm for Potential Problems
In planning the data center migration, assign your project team members the specific task of identifying potential problems. Discuss those problems at each project team meeting, and carefully document recovery plans, back-out procedures, and fail-over options.
Schedule a Trial Run
A trial run of the data center migration allows you to rehearse complex project tasks, identify unexpected problems and potential issues, and make adjustments to the project plan.
Follow the Project Plan
Before the data center migration, check to make sure that all the resources you need will be available. Ensure stakeholders are available to make decisions efficiently should any issues arise. On the morning of the move, begin with a roll call of the relocation team. Then follow the project plan to the letter, to prevent missed steps and out-of-sequence errors.
By validating each task as it is completed, you can verify that the project plan is being followed. Include the following validation elements:
Checklists – Use the project plan checklists to sign off on each task, resolve problems, and verify that all tasks are complete. Have the implementer and project coordinator sign off on each step. This lets you validate what has and hasn’t been done, and helps you avoid post-migration mistakes. Ensure all equipment is inventoried and tracked as it moves from the source to destination location.
Testing – Your end-to-end system test plans allow you to make sure everything is working correctly after the migration. Execute the test plans and document the test results.
Communication – Keep all stakeholders updated in real-time about relocation progress and any issues. Write an executive summary about the migration and distribute it to all appropriate parties, along with the test plan results.
Sign-off sheets – Have the stakeholders sign off to verify that all tasks are complete and all systems are working as expected.
These steps will help you anticipate and overcome problems in your data center migration. Any type of data center move is always a complicated undertaking. If your company doesn’t have the staff, resources, experience, or time to handle a data center migration and all its complexities, don’t try to handle it all yourself.
