HowTo: Move from 2.6 to 3.x via Backup/Restore

[martin]

In-place upgrade from 2.6 to 3.x is not possible (3.x is a 64-bit system). Therefore you need to backup the configuration on the existent 2.6 and restore it to a fresh installed 3.x - and install latest hotfixes or servicepacks, see http://proxmox.com/downloads/category/service-packs

If you restore via GUI, the rule set and the configuration can be restored. In order to get the statistics restored too, you need to backup and restore via CLI.

Backup via CLI
Login via ssh in your existing 2.6 and do the backup

proxbackup -s full-backup.tgz

Copy this backup file to your fresh installed 3.x

scp full-backup.tgz TEMP-IP-OF-PMG3:/root

Restore via CLI
Login via ssh to your fresh installed 3.x and do the restore

proxbackup -c –d -s -r full-backup.tgz

Shutdown your 'old' 2.6

Shutdown and make sure that it will not power on again.

Reboot the 3.x to apply the restored settings

After reboot, check if everything is up and running

I also think that this is helpful info. It was published some time ago but has not lost its relevance nowadays.
