Owner of Ticket is inconsistent

I am trying to upgrade from RT 4.2.12 to RT 4.4.2 but I keep getting this error whenever I try doing
make upgrade-database

The owner of ticket #12950 is inconsistent. The denormalized owner is user #23383, but there exists a normalized owner role group member, user #6. Going to update normalized owner role group members to user #23383. (./etc/upgrade/4.4.2/content:38)

Not sure what’s wrong or how to fix it. Any input will be appreciated

I just had a look in etc/upgrade/4.4.2/content and it appears that the warning is telling you that a ticket has an owner and a group called “Owner” that has a member which isn’t the same as that ticket owner. It appears that after that warning is spat out it removes all the current members of the Owner group and then adds the ticket owner into it, so it should already be fixed for you.
