I have heard that one really should wait several weeks before upgrading 
to a new Ubuntu release (for stability). It seems prudent when 
installing a new version to reserve an empty partition (or add a disk) 
large enough to contain a minimal old version with its non-home data 
then copy config data.

I have been away from Linux for several years so I do not know specifics 
here. Please comment how to determine the size of such a partition and 
what data should be copied. I am concerned about format differences 
between releases.
