The clients have not been upgraded to 12.1 RU2.



Upgrade the SEP clients running on Microsoft Hyper-V guests to 12.1 RU1 MP1 prior to migrating them to 12.1 RU2.

Post migration clean-up:

Upgrade all clients hosted on Microsoft Hyper-V guest VMs to 12.1 RU2 and manually remove or wait for any duplicated entries in the SEPM to reach their age limit.
