Text frames & import layers

In InDesign2017 I need to delete 4 text frames containing old disclaimers information from layer P1 then need to import layers P2 and P3 from a new template. What is the best way to do this?
Find the disclaimers info & delete the contents of those 4 text frames, delete empty frames & then import the layers from the template? I have to repeat this with 200 docs
