is there any other way than export-pst/import-pst to migrate about 200 mailboxes from a old exchange 2007 to a new exchange 2013 server where these systems are not in the same domain, not in the same forest, and there is no domain trust between these both domains?
Source: Windows 2008 R2; Exchange 2007 latest sp/cu; AD: my-old-domain.com
Target: Windows 2012 R2; Exchange 2013 latest sp/cu: AD:my-new-domain-with-no-t
i found this technet-article but it does not help me: https://social.technet.microsoft.com/Forums/exchange/en-US/6b3ff7b1-e9fe-42b7-8f4f-85b882fabde9/cross-forest-mailbox-move-from-2007-to-2013
Thank you very much for help
