Split existing vB5 installation into two subdomains

[ndoktoruser]

Hi!

Thank you for the reply.
I imagined it would be pretty complex, because I would need to know every single place in which vBulletin 5 access the DB.
Now I think that I would need to create tables "searchtowords_[a_z]" for each subdomain, right?
Not to tell about other possible problems that I am not aware of.

I am kind of giving up, but it surprises me that it isn't a request common enough to be added by default.

And yes, I imagined I will need a separate license.

Extra question: is it possible to, at least, share the authentication? I see that private messages would be a different problem, once they are stored in the table node, but it would be really good if users could have an account and be able to access both forums.
