Adding 2012 DC to a 2008R2 domain which still contains a 2003 DC

we need remove legacy 2003 dc, contains certificate role service, want remove domain controller feature. supervisor told class instructor there challenges introducing 2012 dc domain containing 2003 dc. we're not sure if meant 2003-only environment (which doesn't apply us) or environment has 2008r2 dc in (which have, holds fsmo roles).

i have new 2012 server in domain, have not added domain role it, leery of side effects. not have test environment, there details should check before installing 2012 domain role? sharepoint admin (we using sp 2010 sp1) has asked if he'll still able access domain using ldap://domain.com syntax? using exchange 2010 sp3 ru9, there.

in forum post, stated:

it doesn't affect sharepoint functionality @ all. have keep in mind have user profile information synchronized afterwards , check if authentication models has changed. in other words, sharepoint leverages underlying ad infrastructure information, make sure still the same (like domain/domain controllers, authentication types etc)

not sure how validate authentication model.

thanks!

hi,

thanks post.

if want add windows server 2012 dc domain environment, check ensure domain functional level setup @ least windows 2003 mode. lowest required domain functional level allow windows server 2012 domain.

for sharepoint related issue, think ask in sharepoint forums:
