Hi,

i need a help, how i can suspend the replication between the active & passive database copies of the exchange 2016 between two datacenters. we have a major network upgrade which will be lost a communication between datacenters or replication over e-line network.

i want to make a controlled approach rather have it leave like that and face any problems. is it possible? what are the issues i may face once the replication is enabled back.

Thanks
Pavan.

    Suspend the passive copies:
    https://learn.microsoft.com/en-us/exchange/high-availability/manage-ha/suspend-resume-db-copies?view=exchserver-2019#suspend-a-mailbox-database-copy

    Resume it when done:
    https://learn.microsoft.com/en-us/exchange/high-availability/manage-ha/suspend-resume-db-copies?view=exchserver-2019#resume-a-mailbox-database-copy

    Once resumed, give it time to copy and replay the logs. Be patient and just let it do its thing, it may take awhile.

    Wait till
    Get-MailboxDatabaseCopyStatus -Server <PassiveMalboxServer>

    Shows all clear and near 0 on copy and replay

    HI,
    You can use the following commands to suspend/resume copies:

    Suspend-MailboxDatabaseCopy –identity DB1EXCH3 –ActivationOnly  
    Resume-MailboxDatabaseCopy –identity DB1EXCH3  
      
    

    Another option is to block all databases hosted on a server from activating. Run the following command to block all database copies on a server named EXCH1,

    Set-MailboxServer –identity EXCH1 –DatabaseCopyAutoActivationPolicy Blocked  
    

    To reverse your decision, run

    Set-MailboxServer –identity EXCH1 –DatabaseCopyAutoActivationPolicy Unrestricted
