The original Crowd v3.7.2 is connecting to a remote database. This database server is becoming unstable, so I cloned the PostgreSQL database to a new server, and modified crowd.cfg.xml to point to this new database server.
Crowd won't start, with various issues with table cwd_app_licensed_user's columns lower_username, lower_full_name and etc.
I deleted those columns, and restarted Crowd.
Then Crowd says: Could not find application to update: crowd.
I believe I should go back to the original database server, so I modified crowd.cfg.xml to point back to the original database server.
Unfortunately, Crowd then gives me System Error, and most of the content in crowd.cfg.xml is gone!
What can I do now?
