I'm trying to move an azure API management service from tenantA to tenantB
To give third parties the possibility to connect, two app registrations have been created. App registration A is allowed to connect to the API. App registration B is allowed to connect to APP registration A and is used by third partner to connect to the API.

Question: Is it possible to move the API management service to tenantB, and keeping the app registrations from tenantA. So the exisiting app registration(A) in tenantA should be allowed to connect to the api in tenantB

UPDATE

After reading some more, I've come accros multi-tenant applications. Would it be possible to connect application from tenantA to application from tenantB (which is allowed to connect to the api's)? And if so, would it be possible to limit access (not via code)?
