I developed a series of 4 NCM config change templates to use when upgrading a 6500 with 2 supervisor modules. All templates are named Cisco_6500_IOS_Upgrade_Step1 through Step3. Cisco 6500 IOS Upgrade Step 1 NCM Template Cisco_6500_IOS_Upgrade_Step2.ncm-template Cisco 6500 IOS Upgrade Step 3 NCM Template This text file contains the final steps that should be done manually to ensure the IOS loads correctly. You should have run the Cisco 6500 IOS Upgrade ShowCommands NCM Template and Cisco_6500_IOS_Upgrade_Step1 through Step3 templates first. I did not do a template for these steps, but one can be easily made if you are not worried about ensuring commands are compatible and redundancy states. If you are OK with that (not recommended), the template would execute the 'redundancy force-switchover' command, press Enter, and then a yes to save a modified configuration. Then you would have to wait about 20 min and execute it again to get back to the original Active Supervisor module.
