Are old threads getting transferred to the new setup?
They are archived, a link to it at the bottom of the page, “Archived forums”, links to https://www.ratebeer.com/forums/ .
Yeah im not expecting them mass migrated. As i suspect that a difficult job, and where do you draw the cut off.
Id sugest any discussion anyone want to continue you open with link to archived thread and then take it from there.
Its only really gonna be a very short term issue
