Back up the existing system

Before migrating, create a backup (dump) of your database.

For information on backing up the database, please contact your database administrator.

If you abort the converter (runppmconverter) the database tables used by PPM may be damaged permanently. If you start the converter again, it aborts with the following error message:
I: 22.07.09 20:44:09: [CNV] database schema version: -1.0

E: 22.07.09 20:44:09: [CNV] The database was not converted completely. Please restore the database.
Restore the database (dump).

PPM supports the databases Oracle 11g, Oracle 12c, DB2 9.5, DB2 10, as well as SQL Server 2008, 2012, 2014 and 2008 UNICODE, 2012 UNICODE, and 2014 UNICODE and 2014 UNICODE. Detailed information is available in the documentation PPM Database Systems.

Tip

To test the migration outside the productive system you can back up a database dump of the productive system into the database of a test client. For testing purposes, you can perform the migration from there.
