## Selection of the Upgrade Strategy

### Procedure

Select an upgrade strategy that is appropriate for the database instance type, and the source and target versions of the database software. Proceed as described for your chosen upgrade strategy.

If your database instance fulfills the necessary prerequisites, we recommend that you use the program SDBUPD, since an upgrade with this program removes the need for most of the user interaction, and is quicker and safer.
