Our company is planning for Peoplesoft HCM & FSCM Application upgrade from 9.0 to 9.2 (recent PUM) and PeopleTools from 8.52 to 8.58.
What is the ~cerfication~ path for tools upgrade and application upgrade?
Does PT needs to be upgrade first in order to do application upgrade or can you apply recent PUM image that includes latest Peopletools?
Please list all the recommended options and upgrade steps.
