4 Steps to a Smooth Data Center Relocation or Migration
A data center relocation or migration can be a daunting task. Your business undoubtedly relies on technology and data—the collection of essential electronic documents, digital images, electronic transactions, and databases generated as part of your normal business operations. You rely on your data center to manage this wealth of information for you. But if your business is undergoing a merger or acquisition, lacking space or power, or simply has a current data center lease expiring, then you may have no choice but to deal with a data center relocation or migration.
Over the course of our 30 years in business, we’ve helped many companies with their data center relocations and migrations, and we’ve developed a four step methodology that can help reduce your stress (Although, notice we didn’t say ‘eliminate’).
1. Discovery and Data Collection:
- Startup servers and apply new system information (e.g., IP addresses, name etc).
- Assist in veriﬁcation of properly working systems and applications.
- Track, document, and scale data to be replicated.
- Track and document changes to replicated data.
2. Analysis and Design:
- Recommend an appropriate amount of bandwidth to maintain replication of applications.
- Ensure equivalent amount of storage is available at new site.
- Establish IP connection between the two sites.
- Document the external facing IP addresses at old and new sites.
3. Planning and Risk Management:
- Install and implement replication (VVR, SNDR, HORC).
- Begin replication and continue asynchronous replication until fully replicated.
- Prepare DNS propagation within the WWW / internal.
- Switch to synchronous replication to ensure transaction integrity.
4. Complete Implementation:
- 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. While these four steps can certainly help you plan your data center relocation, you still may want to seriously consider the help of a data center relocation specialist skilled in industry best practices and proven methodologies to ensure a successful move.
