Upgrade the Windows OS for Exchange Server 2016 RRS feed

  • Question

  • Hello Folks,

    I have two exchange servers (2016 Version 15.0 ‎(Build 1178.4)‎ in DAG with 2012 R2, I want to upgrade the windows OS on the exchange servers but its not possible.

    My next plan is to install two windows server 2016 servers and install the exchange servers on it but i have a query

    • Can i make the DAG and Mix between 2012 r2 and 2016 OS ( It uses windows failover clustering )

    My target is to upgrade the OS only for the exchange servers, Please suggest some options.

    Thanks, 

    Arif

  • Hi Mohammed.

    It's regular procedure. You install new DAG on same Exchange organization and move mailbox on real-time from old DAG to New DAG. User restart Outlook, when mailbox finish changing DAG.

  • Hi Oleg,

    Thanks for the suggestion !

    So i will install two new exchange servers on windows server 2016 and create a new DAG.

    Then i will move the mailboxes from old DAG to new DAG.

    Finally i will cutover the mail traffic and shift the send connectors from old servers to new servers.
