We are moving away from our windows server to an apple server since the windows server is a decade old and we only have 4 windows machines vs the 26 apple computers and several linux machines. We are a large church but i am part time so I'm trying to do this in a staged shift, we have user shares already moved over to onedrive with out office 365 subscription and global shares will be handled via a synology NAS. So in doing this migration i want to leave some machines on the active directory while i move things over to the open directory. I want to immediately however change the DNS server and DHCP server to the mac server. Will the Active directory or its machine freak out when i do this since it currently handles both? i will of course go in and remove those server roles form the windows server. Will i need to do anything to the client machines left on the AD in the mean time? i know i will have to change the dns server address on the static clients(printers).
