Upgrading from Ubuntu 16 to 18 in-place
I'm looking at doing an in-place upgrade from Ubuntu 16 to 18. Is that a good idea when the server is running Percona?
This cluster has the "Ubuntu 16" bits installed on it. Should I build a new server with Ubuntu 18 and the proper Percona Bionic install?
Or... The easy (lazy) way:
- With a server with Ubuntu 16 and Percona 5.7 (for Xenial)
- Upgrade the server in-place from Ubuntu 16 to 18
- At some point, I would upgrade Percona on this server to Percona 5.7 (for Bionic)
Or is it "not safe" to do #2 and run the Percona Xenial version on it until I upgrade the minor version at some point later?
