Mark — 
You’re right in the mapping between IOS-XE and IOSd blobs.  Based on the older 
architecture of XE — there was a direct correlation between XE and the IOSd 
blob that was running for most of the control-plane bits.

Now that IOS-XE has moved towards “open” IOS-XE — with a drastic difference in 
architecture — 16.6+ is quite different “under the covers” than 3.x versions; 
not that you’ll see much over the top.

Either way — the upgrade won’t be bigly different.

Doesn't seem like a big jump if it is based on the old mapping, where
IOS XE 3.x was actually IOS 15.x. IIRC, it was a way to bring the old
IOS numbering convention into the new IOS XE numbering convention.

So technically speaking, if they were still going to be keeping that,
16.x would translate to IOS XE 4.x.

Someone correct me if I'm mis-remembering.

No, but you might need to use the "force" and or the new  command I got stuck 
on my first upgrade between these versions for hours before finding some 
obscure message board post about the force command.

Something like this:

Switch# software install file flash:cat3k_caa-universalk9.16.06.01.SPA.bin new 
force
Preparing install operation...

Ive upgrade many stacks from 3.6 or 3.7 to 16.x.x code

This message originates from outside of your organisation.

Hi All, have some 3800 running 03.07.04E code, want to upgrade to 16.06.05. 
Seems like a big jump, do I need to upgrade to some intermediate code first?
