Migrating openvz from 3.2 to 5.2

[cecilio albero]

Hello

I have a CentOS openvz running in Proxmox VE 3.2 and I want to migrate to another Proxmox VE 5.2 server

-I make a backup on 3.2
-Copy the backup to 5.2 machine
-Restore on 5.2. No errors
-Start container on 5.2 . It is not working. Console is black with no messages

Any idea?

Yes. Do I need a VE 4.x to migrate from openz to lxc and then change to VE 5.x.? It's not possible do it directly from 3.x to 5.x ?

Yes it's possible
I just did it
And on 6 Vm, only one does not want to start
Try to run it with this to see the error in the log:
lxc-start -n 103 -F -l DEBUG -o /tmp/lxc-103.log
