Is live volume migration supported between different volume types in Red Hat OpenStack Platform?
We have a lot of volumes located on an a specific vendor's SAN storage. This SAN is to be replaced by another vendor's SAN.
We never found a method to migrate volumes without business interruption. Currently, we need to stop the VM, detach the disk, do a retype, reattach the disk and start the VM. This implies a lot of work because we have to get the agreement of the owner of the VM before being able to start the process. Is there a methodology to migrate volumes without business interruption?
