In the last part, we will look at moving the Discovery Search Mailbox from Exchange 2016 to Exchange 2019, to find the mailbox in your environment, you can run the following command:

  • Get-Mailbox discovery*

Now we can move it to the Exchange 2019 Server running a similar command to the other ones:

  • Get-Mailbox discovery* | New-MoveRequest -TargetDatabase “Store1”

Now we can check the progress again by using this command:

  • Get-MoveRequest | Get-MoveRequestStatistics

Once done, you can remove the move requests.

Hope it helps
