try to upgrade vom 4.2 to 6.1, but there is a problem with patch.db-v4.2-migrate-activiti-workflows.
Is there any way to fix this issue (we do not need workflows)?

As the warning suggests, you can't upgrade from 4.2 to 6.x directly with everything successfully working. There may be incompatiblities involved, that's why it is recommended to do incremental upgrade. Ideally from 4.2.x to 5.2.x and then 6.x
