Hey all,
I believe this is an issue that will only occur on stacks. It has to do with us moving from one to two boot codes along with some system max changes that have been made from release to release. The standby unit falls into a boot code mismatch when making this large jump. Please use the following upgrade path as it has been deemed safe:
8030 > 8080e (copy boot/OS images separately via TFTP) > 8090 (use UFI image)
If you are making a large code jump, use 8080e legacy images (non-UFI) as the intermediate stop and you should be okay. You can then upgrade to 8090+ via UFI image.
