How portable are Microsoft SQL databases between editions?

How portable are Microsoft SQL databases between editions? Can you detach and attach databases from say 2005 9.0 express edition and attach to 2008 10.0 enterprise edition? What’s the rules here? I detach copy and attach between like editions all the time without issue, but I wonder how far up or down a database can go, if it can at all. Does “Compatibility Level” play in to portability? Can you detach a SQL Server 2000 (80) Compatibility Level database from a 2008 10.0 standard edition server and attach it to a 2005 9.0 express edition of SQL? What dose a person need to watch out for here?

>> aside from the fact that SQL Express only supports databases up to 4GB<<
Just a very minor quible, that is now 10GB starting in SQL Server 2008.
