Help on outsourcing of departments

Hi there,

we have a customer running >700 SEP clients managed by SEPM.

No we have to prepare one of the customer´s departments for future outsourcing. The department has to act standalone until it is sold.

Should we create another site for this or a completely new "instance" of SEPM within the department? Or, as another option, what is best practice to handle this?

Thank you!

Regards,

Marius
