Upgrade path from 12.4 to 15.1 IOS

[dimitrovski_orce]

Hi all...

I need advice from you guys and gurus here

I finally can upgrade my 1841 routes from 12.4 to the latest 15.1 IOS. Can someone please instruct me about upgrade path , do I need to modify config file and provide me with upgrade instruction link or something like that ?

Thank you in advance

Best Regards

Config file does not need any modification for IOS upgrade, just make sure you keep the backup of the config and the old IOS before reloading the router with the new 15.1 IOS

This document should be able to assist you with the step by step procedure for upgrading the IOS on routers:
