Trying to Update Network

I'm about to embark on updating our networks PMP100 radios.  Most of our radios are running 11.1.  I have finally gotten CNUT to work with my radios.  

Is it safe for me to go straight to 13.4 or do I need to stair set them. Ex. Update to 11.2 then 12.1 ect ect.

I see that you can add multiple packages to the CNUT but I don't know if they will actually update incrementally.  

It may seem like a stupid question but what order should have have the packages in the manager?

11.2

12.1

13.1

13.4

or 

13.4

13.1

12.1

11.2

which ones should I have checked?  If I check them all will the program upgrade them in order or just the first one checked at the top of the list?

For upgrading the PMP 100 from 11.2 you need to go in steps you need to install 12.1 and then 13.4 in steps.

if you still have any query please contact the support at  support@cambiumnetworks.com.  

I have included attachment on how to upgrade software using CNUT.
