I need to make a nameserver change in the whm w/o deleting and reloading the entire site. Can I simply make the 3 changes shown on the image and save and that is all or is it more complicated.. See Image below..
OH.. the reason I am asking is that I tried that and 2 days later still not propagating.. so just wondering if that is correct and if there is a way to run a dns program to see where the blockage is..
It's acceptable to make those changes, however you must also change the name servers at that domain's registrar if you have not yet done so. There's a nameserver guide here you may find helpful:
