Our Client is using PowerBuilder 2019 Build# 2170 for an application. We are going to perform couple of migrations one at a time 1) migrating from 32 bit to 64 bit deployment 2) migrating from PB 2019 to PB 2021. While going through the documentation, i see that NO robust support from Appeon before PB 2022 versions in Introduction page of documentation so which migration can be chosen first to move forward to achieve both of the migrations? Based on that, I will inform the same to client to follow.
