Deleting A records of Servers and moving them to a CNAME

-

hi all,

we migrating navision/sql server new boxes, have many hard coded references records in dns. issue here of course when cut on new servers, applications looking @ old servers , not thing. of course if had pointed cname wouldn't have had problem, digress.

so thinking following:

1.  stop servers registering in dns.

2. delete records of both these servers.

3.  create new record different name. 

4.  use old record fqdn's cname on new records.

this means cut on deleting cname , adding new server's records. when our applications lookup on old records resolve new servers.

the problem though still need old servers , running post migration. know ad relies heavily on dns, able delete server's record , create new record , have still work? or things logging in/group policy/whatever break?

any appreciated.

hello,

in old server's nic properties, uncheck 'register connection in dns' , create record resolves server1.local new server's ip address.

i don't think going 'break' it's have access old server either alias, cname or it's ip address. not accessible server1.local fqdn.
