This topic applies to installations with data sources that are using a database as their data store.
Some releases must modify the database structure. These are performed automatically for you but it is a best practice to perform a backup of your data source beforehand. Additionally If you are in a team environment you must be the sole user connected to the database during the upgrade.
Follow these steps for a successful version upgrade:
1.Ensure you are the sole user of the database during the upgrade process.
2.Backup your database using the DBMS tools.
3.Open RDM while logged in as a user with administrative rights. Please note that you must also be SYSDBA or DB_OWNER.
4.You may be prompted with an upgrade message when your data source is accessed. If so accept the upgrade.
5.Update the client software on all workstations.
