PeopleTools Upgrade - Significance between RELXXX.sql scripts and the PPLTLSCUR84 script
This is a general question about the PeopleTools upgrade process. I am currently in the process of upgrading from PeopleTools 8.53 to 8.55 but this is really a general question about the Tools upgrade process since it has been done this way previously.
When an upgrade is performed, you run the REL scripts to "modify the underlying table structures of the database so that it is compatible with a more recent PeopleTools release" per the Installation Guide.
Later in the process, you copy in the Tools project, PPLTLS84CUR and perform a build which then generates another SQL script to be run. This step seems redundant if the REL scripts already made the necessary database changes.
