Dear Charles, Thank you for your reply. I don't want to make an another storage domain, I just want to do a detach-attach procedure with the existing.
Also, I have an another question. Is it possible delete snapshots in 4.1 what were created in 3.5? How is safe this? I have some vm snapshot in the old system, but I don't want more outage with deleting them.The 3.5 does not support the live snapshot deleting, but the 4.1 yes.
