Hi,

Can you be a bit more specific? Are you migrating a VM from XenServer 7.0 to XCP-ng 8.3?

Im trying to migrate a VM from XEN7 to XCP, like live migration and show this error. I try in cli with similar error

xe vm-migrate uuid=UUID remote-master=IP remote-username=root remote-password=PASSWORD
Performing a Storage XenMotion migration. Your VM's VDIs will be migrated with the VM.

"XEN7": you mean XenServer 7.0 or which version exactly?

Sorry, XEN7 is Xenserver 7.0 Patch 092

Okay so I assume "XenServer 7.0" with patch XS70E092 applied.

IIRC, the gap is too big, so you need either a XenServer 8.0 or 8.1 to migrate first, then you can live migrate to XCP-ng 8.3.

The alternative is to upgrade in place, but it's a big leap too. I would first make a backup of those VMs to be on the safe side.

See https://docs.xcp-ng.org/installation/upgrade/#-upgrade-from-xenserver

Hi!

i need "move" some specific VM not upgrade the pool in this moment.

is possible?

Thx.

pd: export/import is a valid option but take double of time and extra space...

Then use "warm migration" or create a CR job in Xen Orchestra with your VM source on XenServer 7 targeting your XCP-ng 8.3 host. This way, you can validate if they boot on destination.
