Hello,


I am looking for the proper way of updating ISTA. (SDP/BLP) and what has to be changed in the regfile for ISTA to keep working properly.

So if I have the 4.32.15 or 4.39.20 standalone installed, and I want to update SDP/BLP to 4.45.21:
- should I use the istalauncher console and update each version manually with it until reaching 4.45.21?
- should I just update directly the SDP/BLP in the psdz folder? are the language files are supposed to be updated or SDP/BLP is enough?


Until now I have been using the second method from above, with updating directly the SDP/BLP in the psdz folder and updating the regfile with the new version as such: 

Setting: 
"SWIData"="4.45.21"

But there is something I never found out, which line from the regfile refers to the BLP files?

"DataVersion"=
or
"LogisticBaseVersion"=


?


I can't seem to find anywhere a detailed tutorial/instructions on which is which and how to do it the correct way. 


Thank you in advance!
