Photoshop elements 2020& premiere 2020

I started with Adone ALBUM (before what now is ELEMENTS) and have upgraded every few years sincxe then.  I have learned that upgrading can really mess up the database.  So, I am posing a question here:  what explicit steps shouls I take before goinh to 2020?  Details!
