Because we had to move the ivy environment from one server to another, we did a backup of the ivy db and restored it to the new environment (for test and prod).

The convertion on the first system was successful. Trying to convert the Ivy System database on the second we got the error: Failure while system database conversion: Error 'Column names in each table must be unique. Column name 'BusinessCalendarId' in table 'IWA_Application' is specified more than once.' while executing statement 'ALTER TABLE IWA_Application ADD BusinessCalenderId INTEGER NULL'

how can we solve the problem?

Simply make sure the TO-conversion is to an empty database. If you try to convert your database onto an existing database with the same scheme you result in such an error.

As it is a movement on to another server, the ivy system db is not empty at all. it just need to be converted. the first run on the test environment was successful. on the 2nd environment occurs the error mentioned before.

Did you try to convert the system database and it failed and now you are retrying to convert it?

Note that after a failure in converting the database we suggest to restore the database first from a backup before retrying to convert it. Otherwise, some conversions may were executed successful before the failure. In this case the database schema is in a intermediate version that cannot be converted successfully.

Yes we did a restore and tried again. It fails again. The reason: the conversion was done with anohter database user and when we (the customer side as we have no rights to the database-server) dropped the database and did the restore, the new created tables were still there. So the conversion fails again. Now it worked. Thank you.
