To follow on what J.W. noted, we generally suggest only changing one aspect of the environment at a time. If you're planning on changing both the version of Service Desk Manager and your database architecture, I'd strongly recommend choosing one or the other and handing that change one item at a time. Trying to change out both the database and the product version could cause any number of issues, and there are just too many moving parts to reliably identify any issues you might encounter. An added benefit of doing this one step at a time is that you have a good place for backups / snapshots in between, which will help in case you find a need to roll back / restore in case of problems.
