ahh I thought the domains were registered with zoneedit.... will you be using Hover for DNS services as well? If so, click the Tools Tab for the domains and then click the Zone File check tool to get a copy of the zone file in BIND format. You will need that to enter zone data with the new DNS provider. If you are planning to continue using zoneedit for DNS then there is nothing to do save maintaining your zoneedit account so you can make zone file modifications as required.
I hope this helps.
thanks
