So I am currently running a site on PHPBB using no Rewrites. It is currently ranking pretty good on my keywords.. The DB is 4.5gb. Total posts 1696258 • Total topics 989446 • Total members 20669 So my question is how will XF handle the large DB and import? Next what will happened to my Google Ranks? What about the old URLs is there a way to redirect them? Any help would be greatly appreciated.
