Rules behavioral change after application upgrade
Our team is working on an application upgrade from Pega 7.1.9 to Pega 8.5.3. However, we know that there are some rules which the behavior is changed from Pega 7* to 8*.
For example, the data page call: D_DataPage[Parameter:Page.Property]. In Pega 7, specifying the parameter during the call is optional, as opposed to be mandatory in Pega 8. Therefore, any data page call configured in Pega 7 without the parameter specified must be appropriately edited to ensure a correct run of the corresponding feature after the upgrade.
Hence, is there any reference which allows us to easily and accurately identify any rule behavioral change or interpration from Pega 7.1.9 to Pega 8.5.3 ; similarly to the above stated example?
