Jose,
as the others say, it depends.
I managed many GoLives with SAP, which includes PO (purchase orders?) but has a much wider functional range.
I always did a big bang GoLive with all users. Maintaining 2 productive databases offers a bunch of risk in itself (data integrity, 2 applications/processes, how to reconcile). We tended to do it at (financial) yearend to start with a clean slate of transaction for the new year / new application.
We sometimes did prototypes with a small population, but not for productive use. As a project you can play around, but in production you better make sure not to hamper with business.
If, as a scenario, your complete user base is not ready, do not do the GoLive… The problem of incomplete change management should not be solved by slicing data and processes.
