In this article I am taking advantage of Equallogic replication to move VMWare VMs between data centers.
Step 1 Setup Equallogic Replication
Please see my other article on how to configure this
Step 2 Prepare to migrate
To ensure consistency of the VMs I recommend shutting them down and configuring a manual replication to ensure the data in the other data center is a) consistent, and b) up to date
Wait for this replication to complete
Step 3 Promote the Replica Volume
On the destination Equallogic you need to promote the replica volume to make it an actual volume.
Choose the options below
I recommend giving it the same name as the original to keep the VMWare references the same
Setup the appropriate access permissions for your destination SAN.
Click next and finish. You should now see the volume on the destination SAN.
Step 4 Add Volume to ESXi Server
On the ESXi server in the destination data center rescan the iSCSI adapter
You should see the volume appear. You can then browse the datastore for the VMX associated with the VM.
Step 5 Start up VM
Power on the VM and you will probably get the message below.
Select “I copied it” and the VM should startup. Once started you will probably need to change the IP address to that of the new local subnet.
Step 6 Firewall and DNS
The last step you will probably need to do is make any firewall or DNS changes to reflect the change in location of the VM. All done!
