I am currently running 2 DC servers, one is server 2003, the other is 2008r2. The r2 server is virtual and the 2003 is getting old at this point and is in need of an upgrade. What id like to do is migrate the 2003 server to a new physical server running 2008r2 and transfer all of the fsmo roles and set it up as the master dc to replace the 2003 server. What would be the best course of action to do so safely and ensure that the transfer goes smoothly? Is there any complications doing this in a mixed mode environment I need to worry about? From what ive read, this seems like a fairly straightforward process, I just want to make sure I do everything slowly and correctly.
Id like to remove the Server 2003 DC, so that I can replace it with 2008 R2 server and make it a primary DC/DNS server. The virtual 2008r2 server had been running great for months now and id like to keep it as a secondary DC/DNS server. The 2003 DC is currently running AD and DNS.
Any advice as to how I should proceed from here? Is it as simple as doing it in native mode or are there pitfalls I need to be wary of?
Thanks in advance for your replies.
