We have multiple applications for multiple teams hosted on same server and all are using pega OOTB service package- api with basic auth.

Now few teams want to change their authentication type and changing the auth type at OOTB api service package will impact all the application. we are using most of the service of api/v1 and api/v2 so how can we handle this scenarios?

We are thinking save as all the services to different service packages but it seems to not good design. Any help would be very much appreciated.
