  • Hi Kelvin,

    as we have hybrid environment (exchange 2010 & cloud) so below is requirement-

    1. We have two Data center and each data center have 6 DAGs. and each DAG server have two node and each node have 10dbs where 5 dbs are active on one node and other 5 copy are active on other node at same time.

    2. we have CAS/Hub jointly installed on 10 servers.

    We have migrated all users to cloud except 6k users\mailboxes. We will keep just 6000 mailboxes on on-premise environment and rest all around 30K will be on cloud..

    now we want to decommission some DAGs and CAS/Hub Servers and also we want to upgrade our exchange 2010 on-premise server to Exchange 2016 on-premise.

    So please do let us know how can we upgrade our exchange 2010 servers to exchange 2016 and also how much servers (mailboxes and cas\hub servers) are sufficient for 6000 mailboxes.

    Please guide with detailed steps by steps.

  • Hi

    Best would be to use the Exchange calculator to get the requirements.

    Build your new 2016 servers, create your DAG on 2016 and start your mailbox moves.

  • Hi,

     

    Firstly, removing the DAGs one by one through the EAC or the Exchange Management Shell. For more info, please refer to the article: Remove a database availability group 

     

    Please take steps below to update the Hybrid Exchange server to 2016:

    1. Install Exchange 2016 coexist with Exchange 2010.

    2. Switch SCP and services URL from Exchange 2010 to Exchange 2016.

    3. Uninstall the legacy Exchange server.

    4. Run the new hybrid configuration wizard on Exchange 2016.

     

    For more detailed steps, please refer to the assistant guide: Exchange Server Deployment Assistant

     

    If you want, you could migrate the 6000 mailboxes to one Exchange 2016 Server, in guarantee of suffice disk and memory space. I suggest you add more than one Exchange 2016 server in your organization for balancing. You could use

    Exchange Server Role Requirements Calculator to deploy the environment.
