About the arbitration mailbox during Exchange Server migration

Question

Thank you

*The content written in Japanese has been converted to English using a translation application, so I apologize if there are any mistranslations.

Due to the end of support for Exchange Server 2013, we are planning to switch to Exchange Server 2019.

Is there a way to move the arbitration mailbox when migrating to Exchange Server, or is there no problem if I recreate it using "Enable-Mailbox" on the destination server?

Answer 1

Also, here are some of the problems that can occur if you recreate the arbitration mailbox:

The arbitration mailbox may be unable to replicate the other Exchange servers in the organization.

The arbitration mailbox may not be able to perform its functions properly.

The arbitration mailbox may become corrupted.

Therefore, moving the arbitration mailbox to the new Exchange server is best as part of the migration process.

Hi @ sakura_snow_blossom,

You could migrate the arbitration mailboxes from Exchange 2013 to Exchange 2019.

The specific steps are as follows:

1. View the arbitration mailboxes in the two servers separately:

get-mailbox -server “exchange-2013” -Arbitration
get-mailbox -server “exchange-2019” -Arbitration
 

2. Use the following command to move them to the database in Exchange 2019:

get-mailbox -server “exchange-2013” -Arbitration | New-MoveRequest -TargetDatabase "Mailbox Database 2019"

3. Run the following command to check the progress:

Get-MoveRequest | Get-MoveRequestStatistics

4. Finally, you can check Exchange 2019 again to verify if it was successful:

get-mailbox -server “exchange-2019” -Arbitration
