Hi Guys,
I have a vps since 2015 that's currently on Ubuntu 18. I'm planning to upgrade to a more recent version.
The main thing I want is to avoid downtimes. Also don't want to be stuck troubleshooting and fixing an upgrade. If I'm tired of it I want to be able to leave it and come back the next day. What's the best way to achieve this?
Upgrade:
If upgrading I was thinking to save a snapshot, import it on a blank vps, do the upgrade and make it all work and then import the snapshot back into the main vps.
Clean install:
Clean install on a blank vps, snapshot and recover it on my current vps.
What do you think?
Thanks in advance for your help,
