We are looking to upgrade from Premium to Enterprise so our Engineering/IT teams will have their own site and then everyone else will be in another. My question is does that mean each site will have its own service portal or can they all share the same service portal? Just trying to weigh the pros and cons, we have quite a few service spaces that both engineering and non engineering submit tickets to and I just want to make sure I can speak to everything when presenting what I think is the best way forward.
