Hi,
unfortunatetly I've to deal with three domain controllers (Server 2003 R2, FL and DL on 2003) which were used for everything. After about 25 migrations tasks DC#1 and #2 are "free". The third one is "hosting" the most important application for the whole company... pretty cool, I know. 12 years old, compatible with nothing. As you can guess it needs a few months (hopefully) to migrate this application... I don't want to wait that long to go further with the domain migration and update tasks I've in the pipeline. So my plan would be to demote the #3 DC with the application running on it and let it run as a member server as long as it's needed. That way I can update domain to 2012 r2 and go on.
I don't want any approval from anyone of you (I know it's already bad enough). I would like to hear your experience with demoting a domain controller which is hosting another application. Did it work? Any recommendations? Anything?
Application is a "file based" database, with odbc connections to oracle and sql databases (hosted on other systems).
I appreciated any help! Thank you guys!
Thanks, regards, tim
