Roland,
If you need a quick fix to keep you going while you are doing the move
consider using www.zoneedit.com. They allow up to 5 free domains on an
account. Simply set them up as a secondary in your domain registration
after you build out a zone on your new account. Just make the zoneedit zone
a slave to your current zone. If, for some reason your current master (and
public primary) for the zone goes down things will flip over to zoneedit
because they are entered as a secondary. When you get your new stuff up
then you can simply add that into your domain registration and then repoint
your zoneedit account to the new name server. Make sure your firewall and
your server allow zone transfers from whatever name server zoneedit assigns
your zone to. That way it can pull the zones properly.
Hope that helps.
Regards,
Ed Horley
