##Expected behavior The 4.2.3 script from [here](https://raw.githubusercontent.com/GluuFederation/community-edition-package/master/update/4.2.3/upg4xto423.py) upgrades our 4.2.1 instance to 4.2.3 succesfully. ##Observed behavior We tried out the 4.2.3 upgrade successfully on a staging environment and it worked with no problems. However, we're staging the upgrade again as there have been some new clients added in the intervening time. When we try this (on a clone of our production environment - same as our previous successful staging), we get the following output: ``` root@idp42:~# python3 upg4xto423.py Starting upgrade. CONTINUE?
