Downgrade from 4.3.1 to 4.3 topic

I want to downgrade my Samsung Galaxy S3 w/ the AOKP (jb-mr2) 4.3.1 ROM installed back to the AOKP (jb-mr1) 4.3 ROM. Is this possible? If so, do I have to do anything different other than wiping my cache, dalvik cache, and data before flashing the AOKP jb-mr1 4.3 using CWRecovery? Thanks!
