Up until now I have just made a copy of the initial database and used this to create new databases. However if a patch updates the database I can only get one of my databases updated. How do you get the rest of your databases updated?
The DB that is updated is the one that is currently the default.
The only way we have found of updating the other DBs is to use a "spare" machine where we install SD, point it at the DB we want to upgrade, upgrade the SD (which upgrades the DB) and then throw away the SD installation. It is highly unsatisfactory but not found any other way.
