Chris: Yes, I was trying to migrate using these instructions for both 2.4.1 > 3.0.1/3.1.1. The ./setup.py worked fine, I was able to see everything and setup my LDAP Server connection fine. Just missing the ability to import my LDAP user/group data into the new Gluu.
Aliaksandr: That's great news! Luckily they're separate servers so I can just revert to 2.4.1 for now.
Arvind: Thank you for the hard work. Please let me know when the script will be updated.
