Help with Job Data Modernization

Hi,

I am a senior business analyst working for the University of California, we are on HCM 9.2, image 37, PT 8.58. We are implementing Job Data Modernization and looking for guidance and/or best practices. We would like to understand the following:

1. We have a number of custom processes and functionalities which update Job Data, if we implement Job Data Modernization, will we need to all these custom processes and functionalities to point to Job Data Fluid as well?
2. To implement Job Data Modernization, is it required that we implement Fluid Position Management as well, or are they stand alone or can be independent implementations?
