can i still use vBulletin 4.X after upgraded to vBulletin 5.x?
 

Hello

Im now using vBulletin 4.x and my website relies on some Add-ons which i think i should wait sometime after vBB5 is released to get new versions of this add-ons for vbb5. Because i just want to get discount on vbb5 in this september, my question is, if now i upgrade my vbb4.x to vbb5.x, can i still run my website with vbb4.x to wait for releases of add-ons for vbb5?
