@elikyip: no, i didn't find an answer, to be honest, didn't even try to find :) I still have some time until decision, so I wanted to wait for replies in this thread. @hanasakijiji: I haven't used installer, but if it's like this, it shouldn't be a problem. I can use 2 servers during dev, because I want use just 2.1 or 3.0 on production server. Thanks for response.
