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).
Note the database platforms supported by PPM 10.4. Further information can be found in the Software AG System Requirements or in the PPM Database Systems.pdf.
You must upgrade the database platform to a supported platform before you start the migration.
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.
