Question About Legacy Versions and Virus Definitions

Hello,

In my environment we are prepping for an update to take us from Symantec Endpoint Protection 12.1.3 to 14. We have some legacy clients that cannot be updated past their current point, and some devices where we have concerns about updating right away. Will Symantec Endpoint Protection Manager 14 still provide virus definition updates to devices running 12.1.1 and 12.1.3, or will the update leave these devices behind completely?

Thanks

Phil
