restoring proxmox 3.1 node configuration to 3.2 version after reinstall?

Hello,

i want to reinstall my node. Original version was 3.1-21/93bf03d4
According to https://pve.proxmox.com/wiki/Proxmox_VE_2.0_Cluster i have backup of:
tar -czf /root/pve-cluster-backup.tar.gz /var/lib/pve-cluster
tar -czf /root/ssh-backup.tar.gz /root/.ssh

can i restore those files to new installation of version 3.2 without risk, will everything work OK ?

Regards
RH
