Hello. I want to move containers from virtuozzo server to proxmox 6. Here things I done:

I stop container and try:
Code: 
vzdump 0d6c6bf8-ce7f-4be6-a5e0-0ae102e8f323
and get error:
Code: 
ERROR: strange VPS ID '0d6c6bf8-ce7f-4be6-a5e0-0ae102e8f323'
Hmm.. ok, I found that I can change VPS ID and do that by command
Code: 
vzmlocal OLD_CTID:NEW_CTID
Now my ct has 1001 id:
Code: 
vzmlocal d6ed0009-38ff-4cc9-bf38-ee804389db84:1001
Moving/copying CT d6ed0009-38ff-4cc9-bf38-ee804389db84 -> CT 1001, [], [] ...

Hi,

I can only guessing that you can convert your ploop format to simfs if I remember about openvz. You can create a new simfs openvz CT and then use rsync to sync the ploop CT with simfs CT. Then you could convert the simfs CT to PMX .


Good luck!
