Downgrade Database version from 7.18.4.1532 to 7.18.2.1236

Hello community,

I tried downgrading packages to 7.18.2.1236 and everything is working fine. The next thing I need to do is downgrading the database version from 7.18.4.1532 to 7.18.2.1236. Which is the correct way to fix this issue because I'm getting "Versions of application "7.18.2.1236" and configuration "7.18.4" are incompatible"
