I'm having a challenge trying to import a 1.1.0 version survey into version 1.2.3

The DB is a New Install for 1.2.3

The xml import fails with:

Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.

Any suggestions would be warmly welcomed!

I don't see any changes in the XML structure so, it's a DB issue?

*** UPDATE - THe Survey will import questions. It only fails when trying to import answers.

I've emptied the Questions/ANswers/ANswer types and and Survey Tables to try and avoid any conflicts.

Thanks,

Dana
