Exchange 2010 to Exchange 2013 Public Folder Migration

Have you reviewed this article and the reference article (https://supertekboy.com/2014/10/13/2013-public-folder-migration-made-easy/) ?  Gareth makes the process easy to understand and perform.  I hate the MS references for migrating PFs, as they are inconsistent and lacking important content and flow.

First, take a backup--Should go without saying.

Personally, I would take a "snap shot" of the PF permissions that are currently set and remove any orphaned permissions.

Report all PF permissions...

Get-PublicFolder -Identity "\" -Recurse -ResultSize Unlimited | Get-PublicFolderClientPermission | Select-Object Identity,User,@{Name="AccessRights";Expression={$_.AccessRights} } | Export-Csv "C:\PFPermissions.csv" -NoTypeInformation

Select all Open in new window

Check for orphaned permissions...

Get-PublicFolder -Identity "\" -Recurse -ResultSize Unlimited | Get-PublicFolderClientPermission | Where-Object { $_.User -like "NT User:S-1-*" } | Select-Object Identity,User,@{Name="AccessRights";Expression={$_.AccessRights} } | Export-Csv "C:\OrphanedPFPermissions.csv" -NoTypeInformation

Select all Open in new window

Remove all orphaned permissions...

Get-PublicFolder -Identity "\" -Recurse -ResultSize Unlimited | Get-PublicFolderClientPermission | Where-Object { $_.User -like "NT User:S-1-*" } | % { Remove-PublicFolderClientPermission -Identity $_.Identity -User $_.User -Access $_.AccessRights -Confirm:$false }

Select all Open in new window

Lastly, I would ensure that all of the Exchange servers are running supported versions of Exchange 2010 SP3 UR (UR15) and Exchange 2013 CU (CU14).
