IOS Upgrade for 2811 Router

[christopher.morgan]

I have the following IOS on my 2811 Router:

(C2800NM-ADVIPSERVICESK9-M), Version 12.4(5a), RELEASE SOFTWARE (fc3)

I have attempted to use the Software Advisor, Upgrade Planner, Migration Planner and other tools to determine the latest IOS version I can upgrade to.

Unfortunately, the (5a) version doesn't show up in Software Advisor or anywhere else.

Any idea how I can find out the migraine (errr... migration) path?

Hi, if you're happy with the features you've now, the latest would the the highest letter available after 5, I haven't checked what it is now.
