This part of the document contains information about the preparations that you perform before you update your system and migrate your database to the desired target database.

You can prepare for the update while the system is in production operation. Careful preparation of the update is the best guarantee that it runs without errors.

The Software Update Manager supports you by making a range of checks automatically in the preparation roadmap steps (Initialization, Extraction, Configuration, and Checks). To make sure that all requirements are met, run the preparation roadmap steps of Software Update Manager as soon as possible. The successful execution of the preparation roadmap steps is a prerequisite for starting the roadmap step Preprocessing.

You can reset and repeat the preparation roadmap steps as often as you need by choosing Back before you start the actual procedure in roadmap step Preprocessing.
