Hi

 You dont need  to do that:

"

Upgrade

Standard upgrade (i.e. not rolling AP upgrade or ISSU) can be done from the web UI. Once the WLCs are in a HA pair, they run the same version in the same (preferably INSTALL) mode. The web UI upgrade page will take care of distributing the software to both controllers in the pair and will install and reboot both at the same time (causing an identical simultaneous downtime on both)."

  2. HA SSO or N+1?

Save yourself future grief and convert to install mode!

You may need to break SSO to do that.  All the best practice guidance and webinars I've seen recommended using install mode so not sure why you chose to use bundle mode - if you prefer to stay that way then you can expect things to be more complicated whenever you make a change.

Then when you install the software is automatically copied to both chassis.
