I understand that I will need to upgrade to RU6a first and then apply RU6 MP1. My question is if I upgrade the Symantec Endpoint Protection Manager to RU6a and then update that to MP1. Can I just create client packages after the SEPM update and then push out the client package to the SEP MR5 clients? This seems logical to me as the client packages will have both the RU6a and MP1 updates. I have read on Symantec that clients need to be upgrade to RU6a regardless. Thanks.
