So I am preparing to do a cross forest exchange move, Exchange 2010 in a 2008 Forest to Exchange 2013 in a 2012 forest. normal move requests work without issue. When attempting to do a new-MigrationBatch command though, the cmdlet completes successfully but when you check the move request the AllowLargeItems is set to false.
I have set the LargeItemLimit in both the batch CSV and from the Cmdlet itself, this works (the large item count is set right) but the Allow is not changed to true, so all move requests in that batch skip large items. Has anyone else experience this or can they confirm this happens to them when using a migration batch (not sure if the cross forest piece has any play in it or not)
Thanks in advance!
Powershell that is being used to star the batch
New-MigrationBatch -Name BatchName -SourceEndpoint <EndPoint> -TargetDeliveryDomain <SMTP-Domain> -CSVData ([System.IO.File]::ReadAllBytes("BATCH.csv")) -AutoStart -NotificationEmails "Email.address" -DomainController <DC> -AllowIncrementalSyncs $true -BadItemLimit 50 -LargeItemLimit 200 Setting the LargeItem limit to Unlimited also does not help, was hoping but it didn't make a difference.
