Re: Migrating softly
One way is to copy your current database and save it as a new database (using phpmyadmin for example) for the new Tiki version. After testing and so on, with the new Tiki test installation in a separate directory, you could then do the regular update to your current database. This way the current database continues to be used and you don't have to think about which tables contain content. I think it may not be obvious in all cases which tables these are.
