Any caveats on full uninstall, including SQL Server, then reinstall to get SQL Server Express 2012 x64? Moving from 8. to 9. version.

Specifically, which files need to be backed up, then reinstalled (thinking custom dictionaries, preferences, templates, other?)?

When to run the database tuner that updates the SQL server files?

Other considerations/concerns?

Thanks for any thoughts, inputs, cautions.
