It is my understanding that you can use 10.4.11 OD server with 10.5 WGM and get all the wholesome goodness of 10.5 MCX (meaning 10.4.11 schema can already support all the 10.5 MCX stuff) without the apparent problems with 10.5 server and MCX settings not sticking.
I have not witnessed this myself, as my 4 test clients are working great on my test server, however, when I scale to 7500 clients on 4 replicas….I need it to work. If 10.4.11 server is stable and I can get all the 10.5 MCX functions (not worried about any other server functions) then I will stay at 10.4.11. If not, I will have to upgrade to 10.5.3 server (or 10.5.4) and pray that only a minority of users are having issues and I will not be one of them….please oh please….
I should mention that I need all 10.5 MCX to work, including nested computer groups and everything else.
