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.
