I had to replace a server. Backed up the entire system using Clonezilla, created the partitions on the new server exactly as they were (hardware is identical) and then restored the backup onto the new server.
On attempting to boot, I get a couple of ACPI errors and then an error connecting to a data drive that holds no system files and then Ubuntu panics and puts me into a recovery mode with no networking or dns and the zentyal webadmin won't start.
Any ideas where I can even start looking for what's going on?
The hardware is identical, I know the backup is good because I've restored it to the original server before and it was fine.
