I want to replace several WS-C3560X-48PF-E Cisco switches with 2960X. I want the same features enabled and configuration for the ports, the VTY, AAA - everything. What would be the fastest way to clone the old with the new? Copy/paste would need to consider encrypted secrets go to clear text, the self-signed cert section I think should just be omitted and leave what comes with the box. Any other thoughts on speeding the process but not missing anything?
