IOS downgrade

I want to downgrade the current version of IOS software on my Cisco 877w to IOS ver 12.3(8)YI1. I have got some applications which dont work properly with the latest IOS. Where can I obtain these IOS images from?

You obtain IOS images from Cisco. If the router is covered by an active maintenance contract then you are entitled to download different versions of IOS for the router. Is this router covered by an active maintenance contract?

Re: IOS downgrade

is this an extra cost? I might have an old cisco 877 lying around. Can i copy the IOS image from the old cisco 877 to the new cisco 877W?

If there is an active maintenance contract on the router then changing versions of IOS is not an extra charge (but changing feature sets would be). If you do not have an active maintenance contract on the router then there is a charge for the maintenance contract.

Leagally to change the IOS version on the router you should have a maintenance contract. Functionally if you have another 877 you probably could copy IOS from one to the other.

Are you sure about your IOS version? 12.3(8r)YIx is the IOS ROMMON for the 870 series routers not the IOS.
