harikrishna-patnala opened a new pull request, #7611:
URL: https://github.com/apache/cloudstack/pull/7611
### Description
This feature allows the storage migration for ScaleIO volumes between
the ScaleIO storage pools of the same and different ScaleIO storage clusters.
Previously this operation was blocked and now we are allowing it from API/UI.
The volume migration within the same storage cluster is performed using
ScaleIO’s native V-Tree migration operation where the volume will be live
migrated to another storage pool. The volume migration across the different
storage cluster is performed using libvirt’s live blockcopy operation which
will first copy the volume to the destination storage pool and after a
successful copy, the source volume will be deleted. Upon any failures during
the block copy, source volume will remain to continue and other blockcopy
operations will be reverted.
