Yes, it is.
Please see this forum post:
Agents need to have the same or lower version (eg. 6.5, 7.0, ..) than the Collector. Compatibility is guaranteed for Collectors of supported versions, but typically also true for all Agent versions greater than 5.6.
Bootstrapped Agents are upgraded automatically upon restart of the monitored application up to the version of their Collector. Therefore, upgrade first the Server, then Collectors and last the Agents.
Review the component compatibility from the below link:
