I think I've pretty much completed my testing for the db move to the new server.
This process is quite a long one, as the database is pretty massive (28Gb).
I will post a holding page on the site, backup the db, move it to the new server, restore it, then reconfigure everything to point at the new one.
This process could take up to 6 hours I think, so the site will be down from 7am BST tomorrow morning until the job is done.
I'm sorry for this down time, but we should all reap the rewards of it from tomorrow with hopefully a faster site!
