As of now our move to a new server and datacenter will take place on the 6th. The forums will be locked during the move. If all goes well the site will be in a locked state for several hrs, then we switch over to the new server and re-activate the site. In the past we also had to wait for internet DNS to update but not this time so it should happen fairly quickly. If anything changes I'll post an update.
As for the APUG site upgrade this could happen around the 9th or 10th.
