Experimental 4.0 site?
 

I have two sites, both running vB 3.8.4 and vBadvanced.

When vB 4.0 is released I intend to upgrade to the suite. I am really looking forward to the integrated CMS.

Will I be able to operate the new 4.0 sites in addition to the existing 3.8.4 sites until I get everything set up and operational? I don't mean having them go public but on an accessible IP address for the period of time to do the conversion?
