No problem Tom, congrats on the house move
I think you'll struggle to find any hosts that still support TLS1.0, I checked my WHM/Cpanel and the minimum it will support is TLSv1.2, even if you do find something your still stuck with an old depreciated version Might be time to bite the bullet and go along the upgrade route.
Not familiar with Vbulletin since we use phpBB and Joomla, with them version upgrades are "usually" fairly straightforward and painless.
If there's anything I can do to help drop me an email.
