Few days ago I make a copy of my forum* which is vBulletin 3.7.2 Patch Level 2 to make a test site then upgraded it directly to vBulletin 4 Pre Release 4 (suite). The upgrading progress was successful and I has time to test and get familiar with the new functions.
But today* when the Gold version is out* I learnt from the upgrade guide that for the board using older version of vBulletin* we must have the board upgraded to vBulletin 3.8.4 first* then from that point continue upgrading to vBulletin 4 Gold. So I wonder if that a strictly requirement or I'm still able to upgrade to v$ right from v3.7.2?
