How to Change PeopleSoft Database Name

Hello,

I need little bit of understanding on how to change PeopleSoft database name:

This is what the environment currently look like, single instance DB:

PUM DB name: CBDFSM

PUM PeopleSoft DB name: FS92DMO (as it is in PSDBOWNER)

I want to change the PeopleSoft DB name to: FS92PUM

I have done these:

1 - Changed the name in PSDBOWNER to: FS92PUM

2 - Reconfigure AppServer and changed the name in the config file to: FS92PUM

3 - Reconfigure Prsc Scheduler and changed the name in the config file to: FS92PUM

4 - Cleared AppServer and Prsc Scheduler caches
