Do you think that I can import the SDs in my new Data Center
without
any risk to destroy the VMs inside them ??
Thank you for your advice.
If no other engine is managing them, you can safely import the
existing storage domain.
As usual, is always a good idea to keep a backup.
There is no other engine anymore, when you say to keep a backup, you talk about the engine
or ???
What I am afraid is about the Data in the iSCSI SAN, I can't make a backup of this.
