Hi,
I've a cluster on PVE 4.4. This cluster contains ~50 CT.
I'll soon receive a new cluster on PVE 8.

I'm wondering what is the best strategy to migrate the CT from the old cluster to the new. Is the backup/restore the best strategy ? Does this work between 4.4 and 8 ? I don't know if the 8 will be able to restore *and* run the CT. I'll listen of all ideas and strategies :)

Best regards,
Kevin
 
If you go the backup/restore route, remember that if you want to use the unprivileged feature of LXC (default option on restore) and your CTs use systemd, you will need systemd version >=v220 in the containers.
