Hi, Just to make clear what you want to achieve: - DC1 - local storage - host1 - VMs - DC2 - local storage - host2
You want to move the VMs from DC1 to DC2. What you can do: - Add a shared storage domain to the DC#1 - Move VM disk from local SD to shared storage domain - Put shared storage domain to maintenance - Detach shared storage from DC1 - Attach shared storage to DC2 - Activate shared storage - You should be able to register the VM from the shared storage into the DC2 - If you want/need move disks from shared storage to local storage in DC2 Please test this flow with a dummy VM before doing on important VMs. Regards, Freddy On Mon, Feb 26, 2018 at 1:46 PM, Andrei Verovski <andre...@starlett.lv> wrote: > Hi, > > Thanks for clarification.
