Absolutely correct. In an ideal world I try to do this either every other distro in the case of Debian, or go for completely new installations for each new Ubuntu LTS release. Most of the time this doesn't work (normally too many 3rd party repositories, my own fault), so I always have backups handy to help me un-fubar the situation. On my servers things are a lot more predictable, since I rather go for small specialist VMs that does as few jobs as possible. Virtualisation is awesome!
