Yes, I was referring to the INSIDE flash card. The old router failed and I need to replace it. With the flash card swap, this should be a trivial task. Thank you for your prompt reply.
you can do that.Make sure the CF to be inserted has same IOS image as the faulty CF because of any specifc feature which is working with faulty CF and needs to be supported with new CF as well.
It doesn't matter where you transfer the internal flash card to. At the end of the day, you can boot the IOS from the internal flash and the external flash and this is done by setting the correct boot string variable.
