Hi, I have inherited a network running around 80 Win7+ PC's, SQL2000 on WS2003, Filesharing on WS2008R2 + WS2012, and ASP.net/MySQL appn on WS2008R2. AD is on WS2003 at that functional level.
I need to upgrade to WS2016 platform, keeping ASP.net/MySQL appn on WS2008R2 and SQL2000 on WS2003 as is for a few months until they can be retired (some users will require access to all servers).
I am unsure as to whether and how to simply replace (2008) or upgrade (2012) the other servers to WS2016 (leaving ADFL at 2003 for now) moving DC/DNS to new DC's, hoping the WS2003 boxes will continue to function in the new environment, and if so whether to leave the legacy boxes on the existing domain and create a new domain for the other servers etc.
Any related experience or advice gratefully received.
