Running IOS on 3845 router

[johartman]

Can I delete the running IOS from flash on an operational 3845 router to make room for the newer version?  The flash isn't large enough to hold two versions.  Doesn't the IOS get loaded and run from NVRAM?  I don't want to take down an operational router but may have no other choice?

All routers of today run from RAM.

You can safely delete and copy back images while router is running. You can also remove the CF module if you want.
