Upgrading database information requires significant changes and, therefore, a significant amount of database server resources. For this reason, we recommend the following:
-
Upgrade only one plant at a time on a database server.
-
As much as possible, limit other activity on the database server during the upgrade process. You should limit the use of Hexagon PPM products on the server, as well as access to the database by other plants.
-
The more database server resources available for upgrade, the faster the upgrade process will proceed. The more activity occurring on the database server during the upgrade process, the longer that process will take.
