8.3RC2 Backup Pool restore not compatible with 8.3 release

[rexfordnyrk]

Hello All,
Thank you for the help in advance.
I backup my pool and configs of a single XCP-NG 8.3 RC2 instance (Pool master) as I was getting ready to upgrade to 8.3 release. I did an ISO upgrade, which completed without any errors. Fortunately, it kept the IP configuration of the management interface. however all other configs and VMs,SRs. etc, were non-existent and looked like a fresh install. (I know I can manually reattach the SRs, but my problem is the metadata for the various VMs, the various network interfaces and vlans etc)

I got on to XO and tried to restore the pool config that I had backed up to my NAS. However, I got an error message saying that the version was incompatible. Below is the error message.

Is there a way to get this done smoothly, even if it means progressively? ie version after version. I just do not have enough time to set up everything back to the previous configuration. Thank you.

@Nephilim ?Yes I also did save mine. However, it seems to be useless trying to import it into the 8.3 release. Having to set up my pool interfaces and storage again would be pain in the but. for me.
