PSDZDATA change of files only?

[Coolguyat18]

Hi guys, hopefully you might be able to help me?

I have the below software installed:

Ista d + v4.27.22
Ista p v3.67.1
Psdzdata 4.27.20
Esys
Esys launch pro

All above is working lovely (not used esys yet) but I notice there is a slightly newer version of psdzdata out now.

My question is do I have to install all new ista d + and p OR could I simply delete my psdzdata folder and replace with newer files so when I do i level updates with ista or esys it sees the newer files?

Hope this makes sensence lol.
