Note:
If you added records to an alias zone (that is, a zone added to an alias
domain), before you remove the alias domain, make sure you manually migrate
all the records to another zone; otherwise, the added records will be
lost.
However, if you are not using Ensim Pro as your DNS name server, you
do not need to do anything with the DNS settings of Ensim Pro; the settings
shown in the DNS section of the Appliance Administrator GUI are not used.
