Deprecate SSP (Legacy) Requisitions Module

Summary:

What are the steps/actions required to deprecate SSP?

Content (please ensure you mask any confidential information):

I know you can do this by enabling the opt-in 'Enable the Redwood Version as the Default Self Service Procurement Application.' However are there any other steps required? Should we remove certain roles/permissions to ensure users can no longer access SSP? I tried enabling the feature to have RSSP be the default and this removes the SSP tile but people can still access it if it's saved to their favorites.
