Hi Experts
I'm planning to migrated Windows Server 2003 to Windows Server 2013. I'm familiar with all the steps that we need to take care but need your best suggestion to complete this migration.
We have 4 AD sites (Total 8 DCs 2003). I'm planning to decommission one 2003 server which is configured as secondary DNS for clients. Then Will introduce new Server 2012 with same host name and then installing DC role.
Once this part is done, time to decommission primary dns (DC) and installing new Server 2012 R2 with same name of 2003 DC. (Obviously need to remove entries from AD and DNS).
Once all 3 sites are done, then will work on to move FSMO installing one 2012 server as secondary and then will remove primary DC (2003) and again will install last 2012.
I'm taking these steps to avoid DC rename activities because If I introduce new SERVER 2012 DCs in network I have to change their name and IP which is nightmare.
Do you think my planning is ok or I need to follow something diffrent approach?
Thanks Cloudy Lynx
