Migrating from one server to another

I apologize if I missed it, but I'm trying to migrate from one server to another with the intention of decommissioning the old server. The new server is at a new datacenter with a new IP. I've read a few things that describe how to create user or admin backups, but that seems to only be for the user data itself. I get why there's no comprehensive backup system - it's way too involved to implement and manage; too many moving parts.

Is there a checklist of non /home related content that should be copied over for a successful migration? i.e.: DNS data, database data, /usr/local/directadmin stuff, anything else?

It's probably pretty simple to eyeball the stuff in /usr/local/directadmin and manually copy it over, and a mysqldump|mysqlrestore should suffice for mysql stuff, but t's the rest of the stuff that I'm worried about because I have no idea what 'the rest of the stuff' actually is :p

Can anyone share their experiences? Or point me to a post where someone already has? :)

Also, for clarity, does a (admin|user) backup also automatically add the user back to the system passwd file, or does each user need to be created first, data copied then chowed after?

Thanks in advance!
