Changing my TRP from 6 o'clock to POA/POI question

This will probably come off as a rookie question…so be it. I hate the 6 o’clock sight picture that I have to shoot my TRP with and want to change it to a POA/POI at 20-25 yards (my Glock 34’s POA/POI is @ 20 yards). In order to get rid of the 6 o’clock hold, I need to either increase the rear sight height or lower the front sight height, correct? Just wanted to double check before I looked into ordering sights.

correct

Use the formula as nicely explained/illustrated on the Dawson Precision web site:
