.\Prepare-MoveRequest.ps1 -Identity remoteuser@theirdomain.net -RemoteForestDomainController theirdomaincontrollerfqdn -RemoteForestCredential $RemoteCredentials -UseLocalObject -OverwriteLocalObject -TargetMailUserOU "OU=mydomain,DC=net"

Migrate:

New-MoveRequest -Identity remoteuser@theirdomain.net -Remote -TargetDatabase "MDB01" -RemoteGlobalCatalog "theirdomaincontrollerfqdn" -RemoteCredential $RemoteCredentials -TargetDeliveryDomain "mydomain.net" -RemoteHostName "theirdomain.net"

With Bad Items & Suspend:

New-MoveRequest -Identity remoteuser@theirdomain.net -Remote -TargetDatabase "MDB01" -RemoteGlobalCatalog "theirdomaincontrollerfqdn" -RemoteCredential $RemoteCredentials -BadItemLimit 500 -AcceptLargeDataLoss -LargeItemLimit 100 -TargetDeliveryDomain "mydomain.net" -RemoteHostName "theirdomain.net" -SuspendWhenReadyToComplete

Bulk Migration:

Import File:

$InputFile = "C:\Batch01.csv"

Prepare Migration:

Import-Csv $InputFile | Foreach{.\Prepare-MoveRequest.ps1 -Identity $_.PrimarySmtpAddress -RemoteForestDomainController "theirdomaincontrollerfqdn" -RemoteForestCredential $RemoteCredentials -UseLocalObject -OverwriteLocalObject -TargetMailUserOU "Mydomain,DC=net"}

Migrate:

Import-Csv $InputFile | Foreach{Update-Recipient –Identity $_.PrimarySmtpAddress}

Bad Items & Suspend:

Import-Csv $InputFile | foreach {New-MoveRequest -Identity $_.PrimarySMTPAddress -Remote -TargetDatabase MDB01 -RemoteGlobalCatalog "theirdomaincontrollerfqdn" -RemoteCredential $RemoteCredentials -BadItemLimit 200 -AcceptLargeDataLoss -LargeItemLimit 100 -TargetDeliveryDomain "mydomain.net" -RemoteHostName "mail.theirdomain.net" -SuspendWhenReadyToComplete}
