Before Running the Units Upgrade

Before running the units upgrade it is recommended that you run the 12.1 database upgrade on all the Databases in the project as this will make sure that they are writable.

It is also recommended to check the database configuration for your project. In particular, be aware of Dictionary databases that contain Schematic UDAs and identify which Schematic Databases and Projects reference a Dictionary Database (including any Global projects). Step 1 should be run on all Schematic Databases using UDAs in a particular Dictionary Database before Step 2 is run.

Global environments should also be considered carefully to make sure that any Schematic Databases at satellites are covered in Step 1.
