Exchange 2013 to Exchange 2013 Cross-Organization Migration

Cross Exchange Orgs Public Folder migration:
I have 2 Exchange Orgs and 2 Active Directory Forests, and now I'm able to move mailboxes from source Exchange Org to Target Exchange Org.
What about Public Folders? Currently both sides have their own PF hierarchy. How to move public folders from source to target.
Both sides Exchange 2013 (b. 1293.2).

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Thanks for you comment, Mahesh. However, that article which you've mentioned doesn't work for a 2013 to 2013 migration, once Exchange 2010 has Public Folder databases and 2013 doesn't. And it refers to a full PF migration, considering 2013 has not yet PFs created, which isn't the case neither.
The article still applies as with exchange 2013 public folders are also mailboxes and what article essentially does is allowing you to build same PF hierarchy in target as source from script or manually and then do migration from source PF mailbox to target PF mailbox
Regardless of you have existing PF on target or not
And it applies to all exchange versions having modern public folders
Else if u don't want to try, then
Then export public folder as PST at source and import it as PST, that is the only option

You need to check the cross forest migration guide:

You can move mailboxes from Exchange Server 2013 to Exchange server 2013. You can use the Prepare-MoveRequest.ps1 script in the EMS to prepare mailboxes for cross forest moves.

alternatively, you also may try this cross forest migration solution which allows to migrate between exchange servers with real-time coexistence.

In Exchange 2013, the New-MoveRequest and New-MigrationBatch cmdlets are used to peform Exchange cross forest migration.

Download Prepare-MoveRequest.ps1 script and run it using PowerShell on target Exchange 2013 Server. This script will help to copy attributes of AD of source Server to target Server forest.

Here Exchange 2013 Deployment Assistant you can find the exact step-by-step instructions with a distinct checklist on deploying a new Exchange 2013 organization and migrating data to it.
You can also find the steps and procedures to uninstall your previous Exchange Organization in the Deployment Guide: section "Post-configuration tasks" - "Remove legacy Exchange versions".

Another option is pst migration, for this try some solutions like; Shoviv and CodeTwo to migrate easily between exchange server.

Hi Annie, the firt article mentioned at your comment (, is very helpful, and I`m using it to migrate non-PF mailboxes, however it doesn't mention any about PF mailboxes. Then my option would be, at source Exchange Org, to create a new PF Mailboxes and to create a test PF folder and try to move it to the target Exchange Org.
