We just bought a new server. We will transfer all data from old server to new server. Now we are trying to configure new whm. I found in new whm, the value is : Domain Time To Live: 14400, Nameserver Time To Live: 86400 (I do not know if this default value because I am not the first person who login new whm). But in old whm, Both of the fields are blank. So do you think I should just leave "14400/86400" or "blank"?
