If you’ve decided to make the move to a new datacentre, you’re probably deep into planning and assessing the various options out there. To make the process a little easier, see below for a tried and true road map to a successful and pain free migration in just six easy steps.
The key to easy datacentre (DC) migration is to ensure you have a tailored test strategy that incorporates DC Migration Best Practice concepts such as:
- Clearly defined testing stages or phases along with their success criteria (Entry/Exit criteria) like:
- Infrastructure testing – risks around the target infrastructure configuration and specification will be mitigated
- Dry runs and/or dress rehearsals – these will mitigate the risks of utilising unproven/untested migration methods and tools. Assumptions will be validated through these too
- Bundle migration testing. Break up of environments and systems into groups starting from the less critical to the most critical. These will help flush out learnings for future migrations. It usually starts with development environments, followed up by QA environments and finally with production environments bundles
- Schedule/plan your migration events during out of hours to mitigate the impact on business operations. Enough space (usually between 7 to 14 days) must be considered in between migration events
- Like for like migrations are the way forward. Do NOT deploy changes while you migrate. This will increase the risk profile of your project overall and could potentially hinder root cause analysis
- Isolate the migrated systems for testing purposes, this can be achieved by the creation of a network bubble or by making your systems available for specific IP addresses (laptops/PCs). This will protect your environment from possible data loss
- Have a clear roll back plan defined and agreed
- Get senior decision maker and business buy in beforehand and explain potential outages in advance ahead of migration to all affected users
…and that’s it! Following these basic steps will make the difference between a good transition and a bad one. If you’re planning a transition of your own and would like Experior’s experts to help to make it happen right, first time, please don’t hesitate to get in touch.
