I was hoping for some advice on the best process of moving to a new server instance.
I'm currently on a Vultr French server (as no UK ones were available at the time) running Ubunto 16, I want to move to a new UK instance which is running on 18.
I tried updating my existing 16 to 18 but it went wrong and I had to restore a snapshot so don't dare try again. I have a feeling it either removed plesk access or wiped the server, even though I kept all orginal files when asked.
Obviously I can't use snapshots as that will bring over the OS too, but if I just use the backup manager to install a backup what exactly does that move over and what would I need to do seperately? (I'm running muiltiple wordpress sites and some forum software IPB)
