Forum New links in vBulletin 4 compared to vBulletin 3
 

Hi all,

I notice that the links in vBulletin 4 show not a thread ID, but words (which is probably better for search engine optimization). My question is this: what will happen to old links when I upgrade from vB3 - and they still show on Google as the old link ID? Or will Google quickly correct it?

Thanks in advance
