Hi all,

I have to migrate a 1.9 cluster to 2.1 reinstalling all system.

A just want to know if I can use "qm migrate" command between the 2 versions ?

I could do like that:

1/ Install of a new 2.1 host

2/ Creation of the second cluster on 2.1 (only the host for the moment)

3/ qm migrate from a 1.9 host to the 2.1

4/ reinstallation of the old empty 1.9 host

Is that possible ? I don't exactly know how "qm migrate" works, if it needs all hosts in a same cluster or not... (of course all hosts will have access to the same ressources, storage, etc.)

Thank you a lot for your job.
