This will work for moving PFs from 2007 or 2010 to 2013 or 2016
1. Legacy & Destination Server: Download Scripts: Export-PublicFolder PS1 Scripts & Extract to C:\PFScripts\
2. Legacy Server: Export structure
Get-PublicFolder -Recurse | Export-CliXML C:\PFMigration\Legacy_PFStructure.xml Get-PublicFolderStatistics | Export-CliXML C:\PFMigration\Legacy_PFStatistics.xml Get-PublicFolder -Recurse | Get-PublicFolderClientPermission | Select-Object Identity,User -ExpandProperty AccessRights | Export-CliXML C:\PFMigration\Legacy_PFPerms.xml
3. Legacy Server: Locate and rename PFs with “\”
Locate on 2010:
Get-PublicFolderStatistics -ResultSize Unlimited | Where {($_.Name -like "*\*") -or ($_.Name -like "*/*") } | Format-List Name, Identity
Locate on 2007:
Get-PublicFolderDatabase | ForEach {Get-PublicFolderStatistics -Server $_.Server | Where {$_.Name -like "*\*"}}
Rename with:
Set-PublicFolder -Identity <public folder identity> -Name <new public folder name>
Trim folder names with leading or trailing blank spaces
Get-PublicFolder -Identity "\" -Recurse -ResultSize Unlimited | Foreach { Set-PublicFolder -Identity $_.Identity -Name $_.Name.Trim() }
4. Legacy Server: Disable previous migrations
Check for migrations: Get-OrganizationConfig | Format-List PublicFoldersLockedforMigration, PublicFolderMigrationComplete Reset status (may take up to 2 hours): Set-OrganizationConfig -PublicFoldersLockedforMigration:$false -PublicFolderMigrationComplete:$false
5. Destination Server: Disable previous migrations
Check for serial migrations:
Get-PublicFolderMigrationRequest | Get-PublicFolderMigrationRequestStatistics -IncludeReport | Format-List
Remove serial migrations:
et-PublicFolderMigrationRequest | Remove-PublicFolderMigrationRequest
Check for batch migrations:
$batch = Get-MigrationBatch | ?{$_.MigrationType.ToString() -eq "PublicFolder"}
Remove batch migrations:
$batch | Remove-MigrationBatch -Confirm:$false
6. Destination Server: Verify no PFs exist
Check with:
Get-Mailbox -PublicFolder
&
Get-PublicFolder
Remove with (all data will be destroyed):
Get-Mailbox -PublicFolder | Where{$_.IsRootPublicFolderMailbox -eq $false} | Remove-Mailbox -PublicFolder -Force -Confirm:$false
&
Get-Mailbox -PublicFolder | Remove-Mailbox -PublicFolder -Force -Confirm:$false
7. Legacy Server: Create the folder mapping files
Folder name-to-folder size mapping file: .\Export-PublicFolderStatistics.ps1 c:\PFScripts\SizeMap.csv "<FQDN of source server>" Folder-to-mailbox mapping file: .\PublicFolderToMailboxMapGenerator.ps1 "<Maximum mailbox size in bytes>" c:\PFScripts\SizeMap.csv c:\PFScripts\FolderMap.csv
8: Destination Server: Create the Public Folders
Copy c:\PFScripts\FolderMap.csv from legacy to destination c:\PFScripts
.\Create-PublicFolderMailboxesForMigration.ps1 -FolderMappingCsv c:\PFScripts\FolderMap.csv -EstimatedNumberOfConcurrentUsers: "<estimate>"
9: Destination Server: Migrating from 2007 to 2013 Start the migration
Set values: $PublicFolderDatabasesInOrg = @(Get-PublicFolderDatabase) $BadItemLimitCount = 5 + ($PublicFolderDatabasesInOrg.Count -1) Exchange 2013 setup: New-MigrationBatch -Name PFMigration -SourcePublicFolderDatabase (Get-PublicFolderDatabase -Server "<Source server name>") -CSVData (Get-Content c:\PFScripts\FolderMap.csv -Encoding Byte) -NotificationEmails "administrator@domain.com" -BadItemLimit $BadItemLimitCount 2013 Start migration: Start-MigrationBatch PFMigrationStart migration: Start-MigrationBatch PFMigration
9: Destination Server: Migrating from 2010 to 2013 Start the migration
New-MigrationBatch -Name PFMigration -SourcePublicFolderDatabase (Get-PublicFolderDatabase -Server <Source server name>) -CSVData (Get-Content <Folder to mailbox map path> -Encoding Byte) -NotificationEmails "<email addresses for migration notifications>" Start-MigrationBatch PFMigration
10. Check Migration status
Get Status of the migration: Get-MigrationBatch Compare item counts and data size between source and destination: Get-MailboxStatistics -server "post"| Sort-Object datadase,TotalItemSize –Descending | select DisplayName,database,ItemCount,TotalItemSize
11. Legacy Server: Lock Down PFs
Set-OrganizationConfig -PublicFoldersLockedForMigration:$true
12. Destination Server: Finalize the migration
Set-OrganizationConfig -PublicFoldersEnabled Remote Complete-MigrationBatch PFMigration
13. Destination Server: Test and unlock the migration
Set-Mailbox -Identity "Test User" -DefaultPublicFolderMailbox "Public Folder Mailbox Identity"
Then test access from user accounts
14. Legacy Server: Set migration to complete
Set-OrganizationConfig -PublicFolderMigrationComplete:$true
15. Destination Server: Set migration to complete
Set-OrganizationConfig -PublicFoldersEnabled Local
