This example creates a public folder migration request from the Exchange 2010 source public folder database PFDB01 and uses the CSVData.csv file that was created using the Export-PublicFolderStatistics.ps1 script. For more information, see Use serial migration to migrate public folders to Exchange 2013 from previous versions.

New-PublicFolderMigrationRequest -SourceDatabase PFDB01 -CSVData (Get-Content C:\PFMigration\CSVData.csv -Encoding Byte)

Migrating public folders is a multi-step process. For more information before you attempt a public folder migration, see Use serial migration to migrate public folders to Exchange 2013 from previous versions.

Parameter Required Type Description

OutlookAnywhereHostName

Required

Microsoft.Exchange.Data.Fqdn

This parameter is reserved for internal Microsoft use.

RemoteCredential

Required

System.Management.Automation.PSCredential

This parameter is available only in the cloud-based service.

The RemoteCredential parameter specifies an administrator who has permission to perform the migration request, for example, Administrator@humongousinsurance.com.

This parameter requires the creation and passing of a credential object. This credential object is created by using the Get-Credential cmdlet. For more information, see Get-Credential.

You must use this parameter in conjunction with the RemoteMailboxServerLegacyDN parameter.

RemoteMailboxLegacyDN

Required

System.String

This parameter is available only in the cloud-based service.

The RemoteMailboxLegacyDN parameter specifies the mailbox of the remote credentials specified in the RemoteCredential parameter.

You must use this parameter in conjunction with the RemoteMailboxServerLegacyDN parameter.

RemoteMailboxServerLegacyDN

Required

System.String

This parameter is available only in the cloud-based service.

The RemoteMailboxServerLegacyDN parameter specifies the server legacy distinguished name (DN) of the back-end server. To find the LegacyExchangeServerDN property, run the following command: Get-ExchangeServer <Identity> | Format-List LegacyExchangeServerDN.

SourceDatabase

Required

Microsoft.Exchange.Configuration.Tasks.DatabaseIdParameter

This parameter is available only in on-premises Exchange 2013.

The SourceDatabase parameter specifies the identity of the database on which the public folders that are being migrated resides. You can use the following values:

  • GUID of the database

  • Database name

AcceptLargeDataLoss

Optional

System.Management.Automation.SwitchParameter

The AcceptLargeDataLoss switch specifies the request should continue even if a large number of items in the source mailbox can't be copied to the target mailbox. You need to use this switch if you set either the BadItemLimit or LargeItemLimit parameters to a value of 51 or higher. Otherwise, the command will fail.

AuthenticationMethod

Optional

Microsoft.Exchange.Data.Directory.SystemConfiguration.AuthenticationMethod

This parameter is reserved for internal Microsoft use.

BadItemLimit

Optional

Microsoft.Exchange.Data.Unlimited

The BadItemLimit parameter specifies the maximum number of bad items that are allowed before the request fails. A bad item is a corrupt item in the source mailbox that can't be copied to the target mailbox. Also included in the bad item limit are missing items. Missing items are items in the source mailbox that can't be found in the target mailbox when the request is ready to complete.

Valid input for this parameter is an integer or the value unlimited. The default value is 0, which means the request will fail if any bad items are detected. If you are OK with leaving a few bad items behind, you can set this parameter to a reasonable value (we recommend 10 or lower) so the request can proceed. If too many bad items are detected, consider using the New-MailboxRepairRequest cmdlet to attempt to fix corrupted items in the source mailbox, and try the request again.

NoteNote:
If you set this value to 51 or higher, you also need to use the AcceptLargeDataLoss switch. Otherwise, the command will fail.

BatchName

Optional

System.String

The BatchName parameter specifies a descriptive name for the public folder migration batch. You can use the BatchName parameter as a search string when you use the Get-PublicFolderMigrationRequest cmdlet.

CompletedRequestAgeLimit

Optional

Microsoft.Exchange.Data.Unlimited

The CompletedRequestAgeLimit parameter specifies how long the request is kept after it has completed before being automatically removed. The default CompletedRequestAgeLimit parameter value is 30 days.

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm switch can be used to suppress the confirmation prompt that appears by default when this cmdlet is run. To suppress the confirmation prompt, use the syntax -Confirm:$False. You must include a colon ( : ) in the syntax.

CSVData

Optional

System.Byte[]

The CSVData parameter specifies the mapping file output generated by the PublicFoldertoMailboxMapGenerator.ps1 script. Use this parameter for local migrations. This parameter can't be used in conjunction with the CSVStream parameter. You must use this parameter if you don't use CSVStream parameter.

CSVStream

Optional

System.IO.Stream

The CSVStream parameter specifies the mapping file output generated by the PublicFoldertoMailboxMapGenerator.ps1 script. Use this parameter for remote migrations. This parameter can't be used in conjunction with the CSVData parameter. You must use this parameter if you don't use CSVData parameter.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

This parameter is available only in on-premises Exchange 2013.

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.

InternalFlags

Optional

Microsoft.Exchange.Management.RecipientTasks.InternalMrsFlag[]

The InternalFlags parameter specifies the optional steps in the request. This parameter is used primarily for debugging purposes.

LargeItemLimit

Optional

Microsoft.Exchange.Data.Unlimited

The LargeItemLimit parameter specifies the maximum number of large items that are allowed before the request fails. A large item is a message in the source mailbox that exceeds the maximum message size that's allowed in the target mailbox. If the target mailbox doesn't have a specifically configured maximum message size value, the organization-wide value is used.

For more information about maximum message size values, see the following topics:

Valid input for this parameter is an integer or the value unlimited. The default value is 0, which means the request will fail if any large items are detected. If you are OK with leaving a few large items behind, you can set this parameter to a reasonable value (we recommend 10 or lower) so the request can proceed.

NoteNote:
If you set this value to 51 or higher, you also need to use the AcceptLargeDataLoss switch. Otherwise, the command will fail.

Name

Optional

System.String

The Name parameter specifies the name of the public folder migration request.

Organization

Optional

Microsoft.Exchange.Configuration.Tasks.OrganizationIdParameter

The Organization parameter is reserved for internal Microsoft use.

Priority

Optional

Microsoft.Exchange.MailboxReplicationService.RequestPriority

This parameter is available only in on-premises Exchange 2013.

The Priority parameter specifies the priority setting that you want to use for the migration to be completed. This prioritizes against any Microsoft Exchange Mailbox Replication service (MRS) process. This parameter accepts the following values:

  • Lowest

  • Lower

  • Low

  • Normal

  • High

  • Higher

  • Highest

  • Emergency

If you don't specify a value, the default value is Normal, which means that the request is prioritized by the time and date it was accepted into the MRS queue.

SkipMerging

Optional

Microsoft.Exchange.Management.RecipientTasks.SkippableMergeComponent[]

The SkipMerging parameter specifies whether certain stages of a public folder migration are skipped for debugging purposes. Don't use this parameter unless directed to do so by a Microsoft Customer Service and Support or specific documentation.

Suspend

Optional

System.Management.Automation.SwitchParameter

The Suspend switch specifies whether to suspend the request. If you use this switch, the request is queued, but the request won't reach the status of InProgress until you resume the request with the relevant resume cmdlet. You don't have to specify a value with this switch.

SuspendComment

Optional

System.String

The SuspendComment parameter specifies a description about why the request was suspended. You can only use this parameter if you specify the Suspend parameter.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.

WorkloadType

Optional

Microsoft.Exchange.MailboxReplicationService.RequestWorkloadType

This parameter is available only in on-premises Exchange 2013.

The WorkloadType parameter is reserved for internal Microsoft use.
