Hi,

my migration stucked here:

I found the fix:

„3. Migration stops due to MySQL errors
On systems that experienced problems with an upgrade in the past, the migration process may stop due to MySQL errors in the tables ticket and ticket_history. Usually these errors are NULL values in the source table that are no longer allowed in the target table. These conflicts have to be manually resolved before you can resume the migration.

There is a check in migration.pl that checks for NULL values before the data transfer is done. Note, that the resolution still needs to be performed manually.“

But I’m not sure how to apply it. Can someone help?
