Pretty much as the subject line says! When creating a rulebase in 10.3 OPM automatically creates public names (for containment relationships) when you name the forward and reverse relationships. When you open the project in 10.4 and run the upgrade wizard on the rulebase it doesn't carry the relationship public names across. Then if you try to build the rulebase as a module it says it can't export the entities as the relationships have no public names and you then have to go through all the relationships and enter by hand.
Am I missing something here?
No you didn't miss anything. There might be a bug in the upgrade process which only affects containment relationship.
I have logged this to be fixed in future release.
