If you change screening service that integrates with Taleo, then what happens to the Taleo data?

If your organization changes Screening Services that leverage a Passport connection, what happens to the data that is currently in the system?  To clarify, if you've been using background check Company A, and have 1000's candidates/hires that have data tied into the Screening Services section of the candidate record (in Taleo) and then you switch to Company B. What happens to that data in Taleo, does it stay? Will you be able to see it or does it get wiped out?

Curious whether in your efforts of scoping a new screening service that integrates with Taleo whether it required some consideration for some of the data that resides in Taleo already from a previous vendor.
