Hello, this is my situation. Downtime of the VMs is not a problems as it is a test environment all based on 3.2.1 on f18 and ovirt stable repo DC1 FC type with cluster1 2 hosts connected to 7 FC LUNs power mgmt configured live migration ok overall 11 VMs DC2 FC type with cluster2 1 host (it has access to all the LUNs of DC1from a SAN point of view, but not configured at the moment) DC1 has ovirtmgmt without vlan tagging DC2 has ovirtmgmt with vlan tagging I would like to move all storage domains and VMs into DC2 and then redeploy the DC1 hosts in DC2 so that I have a three nodes cluster with a vlan tagged ovirtmgmt in DC2 and I delete DC1 How can I move storage domains from DC1 to DC2 without exporting/importing VMS? Can I "simply" detach" them one-by-one from DC1 and attach to DC2? Will the VMs automatically be part of DC2 and its cluster cluster2 (apart from eventually reconfigure their network)? Thanks, Gianluca
