I managed to find the missing salt file. I had to change the update script to look in the new location.
However, now I get this error
[root@OAuthSRV-clone ~]# python update.py -o
Ready to upgrade Gluu Server. Start now (y|N) y
This upgrade replaces all the default Gluu Server scripts WITH SCRIPTS FROM 4.0
and removes other custom scripts. (This will replace any customization you may
have made to these default script entries) Do you want to continue? (Y|n) Y
Keep users' inum as it is? (y|N) N
