"Best Practices for Implementing Autodesk Vault" says that "You can upgrade MSDE to full SQL Server at any time."
Does it mean that it is just a matter of licensing? Or, will I have to perform some tedious job like baking up all data, installing full SQL Server, migrating data to new installation, testing database, etc??
Of course I highly recommend doing a backup with the ADMS Console prior to doing any kind of upgrade, but the upgrade process generally will not involve restored the backup unless something goes very wrong.
