For multiple BU, multiple times implementation project for subscription management setup required ?

Hi everyone,

Our business for client is under BU - ABC and the current subscription management implementation is live and working fine.

Under Define Business Unit for Sales> all the setups are done with BU 'ABC'

Now there's another business that need to be added with BU - XYZ for Subscription Management, so wanted to understand whether we need to implement a new separate project for subscription management and setup everything with this new BU ?

It would be really helpful, if anyone who knows can answer this asap.
