We are trying to migrate from MS Exchange Server 2007 to MS Exchange Server 2016.
As a first step we set up MS Exchange Server 2013 on a temporary server. Then all mailboxes and public folders were migrated from ES 2007 to this temporary ES 2013 database.
After that we deployed MS exchange Server 2016 on a different server and tried to move all mailboxes from the temporary ES 2013 on this new server. Mailboxes were moved perfectly. All public folders mailboxes were moved easily excluding one (named PFMailbox01) which holds main public folders hierarchy.
We try to move this public folder mailbox using the command:
New-MoveRequest "PFMailbox01" -TargetDatabase "Public Folder Database 2016"
We monitor the process using
Get-MoveRequest "PFMailbox01"|Get-MoveRequeStstatistics|fl
Everything goes well until the process reaches the progress point 94%. At this point moving slows down. Then in several minute process progress drops down to 20% and following errors are posted to Windows Application log:

We also tried to move this mailbox to another Exchange Server 2013 database. The result was the same.
We can not just refuse from this mailbox as it contains main public folder hierarchy.
Please, help us to overcome this error.
Or may be we can recreate main hierarchy in another mailbox directly on MS Exchange server 2016 and then just remove the old one?
Kind regards, Evgeny
