Get-PublicFolderMigrationRequest doesn´t shows PublicfolderMigrationRequest..and cant create new one..

I tried to migrate PF from EX2007 to EX2013, but i  ran into an error and made the

[PS] C:\Windows\system32>New-PublicFolderMigrationRequest -SourceDatabase (Get-PublicFolderDatabase -Server xyz) -CS
VData (Get-Content C:\pf\Foldertomailboxmap.csv -Encoding byte)
You cannot perform two types of Public Folder migration at the same time.

I would like to remove "old" Set-OrganizationConfig -PublicFolderMigrationComplete:$False, but i cant, cause it is not listed..

I removed and recreated Publicfolders in Exchange2013  and "Set-OrganizationConfig -PublicFolderMigrationComplete:$False" is also set. Is there a low Level method with adsiedit to remove pending PublicFolderMigration
