Hi @Johnny Broe ,

Welcome to the Microsoft Q&A platform!

Based on your description, you want to move the public folder database from the old Exchange 2019 server to the new Exchange 2019 server on Windows Server 2022. Here is a high-level overview of the process:

1. Prepare the environment:

• Make sure both the source and target servers are fully updated.
• Verify that the public folder hierarchy is in a healthy state.

2. Initiate the move using the New-PublicFolderMoveRequest cmdlet. This cmdlet moves the public folder content from the source public folder mailbox to the target public folder mailbox.

Example:

New-PublicFolderMoveRequest -Folders \PublicFolder1 -TargetMailbox TargetPFMailbox

3. Use the Get-PublicFolderMoveRequest and Get-PublicFolderMoveRequestStatistics cmdlets to monitor the progress of the move request.

Example:

Get-PublicFolderMoveRequest | Get-PublicFolderMoveRequestStatistics

4. Once the move request is complete, you need to remove the move request using the Remove-PublicFolderMoveRequest cmdlet.

Example:

Remove-PublicFolderMoveRequest -Identity <RequestIdentity>

5. Check the target public folder mailbox to make sure everything has been moved successfully. Verify that users can access the public folders without any issues.
6. After verifying that everything is working properly on the new server, you can decommission the old Exchange 2019 server if it is no longer needed.

Note: It is critical to perform a full backup of the public folder database before starting the move process. Also, consider performing the move during a maintenance window or low-usage period to minimize the impact on users.
