Yes, a stepped upgrade is required on the platform. However at 2.1 you're good to just go straight to 2.3.

This is from the 2.3 release notes:

SOFTWARE UPGRADE
Pre-requisites
CNUT Version 3.20.19 or later
CAP Version e2.1 or later ((PMP 320 System Release e2.1 or later)
CSM Version 6.5.1 or later (PMP 320 System Release e2.1 or later)
