Hello Ilya,
Thank you for your question and for reaching out with your question today.
In Exchange Server 2019, the ability to disable database indexing before migration is not directly supported through a built-in function. However, you can achieve a similar outcome by following these steps:
- Stop the Microsoft Exchange Search and Microsoft Exchange Search Host Controller services on the Exchange server that hosts the mailbox database you want to migrate.
- Open the Exchange Management Shell on the Exchange server.
- Disable automatic database provisioning temporarily by running the following command:
Set-MailboxDatabase <DatabaseName> -IndexEnabled $False
Replace <DatabaseName> with the name of the mailbox database you want to disable indexing for.
- Verify that indexing is disabled by running the following command:
Get-MailboxDatabase <DatabaseName> | fl Name,IndexEnabled
Ensure that the output shows IndexEnabled as False for the specified mailbox database.
- Proceed with your migration process. Once the migration is completed, you can re-enable indexing by following the next steps.
- Start the Microsoft Exchange Search and Microsoft Exchange Search Host Controller services on the Exchange server.
- Enable indexing for the mailbox database again by running the following command:
Set-MailboxDatabase <DatabaseName> -IndexEnabled $True
Replace <DatabaseName> with the name of the mailbox database.
- Verify that indexing is enabled by running the following command:
Get-MailboxDatabase <DatabaseName> | fl Name,IndexEnabled
Ensure that the output shows IndexEnabled as True for the specified mailbox database.
By temporarily disabling indexing and re-enabling it after the migration, you can effectively prevent the mailbox database from being indexed during the migration process. However, keep in mind that this approach should be tested thoroughly in a non-production environment before applying it to a live Exchange Server deployment.
