Renaming a Domain Controller

Question

Hi,

I would like to ask if there will be issues if I rename our domain controller? 

I see a steps from microsoft from the link below.

https://technet.microsoft.com/en-us/library/cc816601(v=ws.10).aspx

But I'm not sure if Changing the hostname of our domain controller may cause any issues.

Currently we are upgrading our DCs' from 2008 R2 to 2012 R2.

There are application server that is using our DC's as DNS  Most of it are pointing to IP address and some are pointing to the Host name of the DC. Also, we are not sure if there are LDAP connection that is using the DC's host name. We had an issue before when we demote the old 2008 r2 dc and promote 2012 r2. In the middle of the replication, some application servers seems to be throwing dns query to the new DC. It seems that it detects that the DNS server in the DC is already active. Since the DC is not finish yet in the replication (somehow the dns database is not yet complete), the application server cannot resolve any queries. Also, the application server didn't fail over to its secondary DNS because it detects that the primary DNS server is active. When we stop the dns server service of the DC, the issue was gone. The application server, throw dns queries to its secondary dns.

So our way to upgrade our DC is to use a different hostname and IP then we will rename it after the replication has completed.

Im checking if renaming hostname may cause any major problems.
