Hi there!
When migrating between storage systems, I've found the easiest approach is to consider your migration options from closest to the application, down to the bottom of the stack - storage.
For example, I'll usually take this approach at a high level when planning:
- VMWare - Use Storage VMotion to move VMs to new storage
- Exchange - Use DAG replication to add in new constituents on new storage and then evacuate old ones
- iSCSI or FC attached LUNs - Volume manager replication and physical volume replacement (LVM, VxVM, Windows Dynamic Disk replication)
- CIFS or NFS shares - We have a tool called XCP that can do very fast copies, enabling a quick cut-over
- iSCSI or FC attached LUNs - Where no volume manager is available or where considerations dictate, we can perform Foreign LUN Import (FLI) to bring LUNs into the system, or we have professional services option for low outage cutovers using a rented DTA2800 appliance
In terms of compatibility, for LUN (SAN) based storage we have two components - the Host Utilities Kit and the SnapDrive MPIO DSM - which we recommend be installed.
Hope this helps! Please feel free to post any followup questions.
