@olivierlambert I understand that, just for the migration purposes is all.. some of these migrations take months, if not years to get complete, and having it all under a single hood while that migration work is being done would be nice... I know that it is a HUGE ask

Have successfully migrated 2 VMs from ESXI, doing MANY Hyper-v migrations, and have a suggestion / feature..
THIS is likely not the forum for this, but I know you guys are in a similar situation...

Is it possible to add within XOA or the XCP-ng Center to allow attaching to a hyper-v cluster and do drag and drop style of migrations from hyper-v to XCP?
I had something similar setup for a past company that allowed me to attach to any type of cluster and manage all from within a single pane of glass ( Until all migrations were complete )

@florent none of the drives are over 2tb, largest is 900GB, so I will assume it is due to snapshots?

Drives are
127GB
900GB
325GB
250GB
500GB

@florent thanks! for the fast reply, I will take the outage and rerun, and let you know outcome.

After running for hours, get the following
