Is it okay if I install a previous version of Vbulletin with a vb4 suit license?
 

I would like to know if it's okay or not to install vbulletin 3.8.4 and have it active while also have an installation of vbulletin 4.x(inactive) to work with and get it ready for my site? Once I will be done with 4.x, I would just replace 3.8.4 with 4.x.

I want to be sure before i make a move.

thanks
