  • In case a downgrade to a previous version is necessary:
    • For a downgrade you have to review our downgrade documentation.
    • Simply replace the PowerFolder-Server.jar file with that from the previous version you would like to run.
  • Log messages due to the higher schema version of database can be ignored:

    • [DatabaseMigrator]: Database layout version is newer than expected.
