A quick one and hopefully you don’t get to see this moving forward.
Long time ago Cisco used to provide images on CCO that were divided in 2 parts, for upgrades and patches, I started working with those images since everybody started migrating from older versions to 9.x which is when I officially working as a consultant.
How to join or combine these 2 ISO image?
