Restore pmx 5.4 VM on Proxmox 6.4 PVE

[Mjp9119]

Hi,
I´m trying to restore a VM backup made on a PVE running Proxmox v5.4

The new PVE ( where I want to restore the VM backup ) is running
Proxmox v6.4

My question are:

Are version 5.4 backups restoreable on a 6.4 version ?

Should I expect any problems on the process ?

Thanks in advance
Mauricio

That should work without problems.

Hi thanks for the reply:

Unfortunately I've had this warnings while restoring

After that, the restore started displaying 1% .... but it seems to freeze

I´ve retried several times the operation with no success

As I couldn't wait any longer, "solved" the problem by downgrading proxmox version to 5.4 and restored the backup without any problem

I'm just sending this information in case it could be useful to anyone.
Thanks !!
