In our last two blog posts, we’ve covered some best practices for data center relocations. The first discussed the need for a proven methodology before beginning any data center migration while the second highlighted the first two recommended phases – discovery and data collection, analysis and design. This blog addresses the final two phases when undertaking a data center relocation – planning and risk management and the complete implementation itself.
Planning and Risk Management
Once you’ve selected a migration plan, you should assemble all previously collected data and documentation into an inclusive Data Center Migration plan, complete with an in-depth risk analysis. This plan should encompass floor layouts and rack diagrams, outline the exact tasks to complete the relocation, and chart the matrix of the migration priorities. And because your data system likely contains complex interdependencies between your business-critical applications and assets, you’ll need to provide detailed dependency mappings of your data center.
This comprehensive up-front planning and risk management ultimately ensures minimized risk and downtime so you can keep your business running smoothly without endangering your business-critical data and applications.
Lastly, you’ll apply the comprehensive plan to relocate your data center and successfully implement the data center move. You’ll need to manage exit plans with your current facility and the installation plan with the target facility—making the transition and switch over as smooth as possible.
To complete the switch over:
- Shutdown applications at old site
- Suspend Replication
- Propagate DNS entries to WWW / internal
- Startup applications at new site
- Test applications using external and internal connection
- Fail-back to old site, if required
- Restore hardware/data if applicable
- Manage the entire project, including the formal project plan and coordination of all parties
Data center relocations and migrations always pose a serious threat of disruptions or data loss that can jeopardize your crucial business operations. If you’re serious about your business, then disruptions and data loss are unacceptable risks. Whether you’re making a cold move of your existing equipment, a hot move of existing equipment, or a hot move to new equipment, following a proven methodology, along with these four phases, can give you peace of mind.
