Migrating to Exchange 2013 from Exchange 2010. Created Ex 2013, moved some mailboxes OK. Then could no longer move mailboxes. No errors. The Migration email says complete. Synced: none, Total Mailboxes: none.
Tried several mailboxes. Same result.
Ex 2010 is SP3 RU6, (at least it says RU6 is installed in Programs/Features. The build is for SP3 w/o RU6???)
Ex 2013 is SP1 aka CU4.
How to proceed???
