We have just recently Upgraded act from Act 10 to Act 12 since the Upgrade we are unable to see or edit the Criteria for Dynamic Members in groups which had been migrated.
If I read this correctly - in the first database conversion you have problems with the existing Groups and creating Criteria. In a second conversion (test environment) you can edit the pre-existing Groups.
It sounds as if the conversion had an issue. If you are still having a problem in the production database and have the backup from before the conversion, you can restore it using 'Restore As' (to a new name) and then convert the database again. Since the conversion was successful in the test environment, I would do the Restore there and convert it. Then you can use Backup/Restore to move the newly converted database to the production environment.
