i have more than 2500 clients and some clients are having windows xp and windows 2003
i have 12.1 two servers one is active and second is replica and i have SQL on both servers and replication time is 1 AM over the night daily
now i want to upgrade version 14 but i want to keep version 12.1 servers to get update for windows xp and 2003 server. i have more than 50 remote sites and each site i have one GUP and the link speed is only 1 Mbps if i upgrae from 12.1 to version 14, than version 14 SEPM doesn't support 12.1 definition and clients with 12.1 will not update the latest definition and on remote site i can not upgrade my all clients on a single day because i dont have any SCCM or desktop manager so i have to use autoupgrade through SEPM server
i am looking a solution that i will keep old servers and add new servers as well version 12.1 will communication with old sepm and version 14 will communication with sepm 14
i will upgrade version 14 but its time taking once i will upgrade all client i will remove sepm 12.1
can you please suggest me what to do and how to do ?
Thanks
