Hi,
I have a core switch which has two supervisors as shown below:

I need to remove the secondary Supervisor to another core switch which is the same model, in order for the two Cores to have the same Supervisor and configure VSS since now the customer has SPOF with his core switch.
The Core Switch OS is below:

I knew that VSS isn't supported by the recent versions of OS and Rommon based on the below:
Virtual switching system (VSS) can enable on Catalyst 4500/4500X series switch (Supervisor Engine 7-E, Supervisor Engine 7L-E, and Catalyst 4500-X). Cisco IOS XE 3.4.0SG and ROMMON IOS Version 15.0(1r) SG7 later released support VSS. This document discuss about Cisco 4500 SUP7-E ROMMON upgrade.
My questions that I need help with are the following:
1- What is the recommended way to remove the secondary supervisor and plug it into the other core switch. Shall i turn off the power of the core and then remove it and plug it to the other one. Or i can remove while the core is powered on and avoid downtime, is this possible without the secondary supervisor crashing.
2- The minimum for OS and Rommon to support VSS is Cisco IOS XE 3.4.0SG and ROMMON IOS Version 15.0(1r) SG7. However, the recommended OS for the supervisor on Cisco website is Release 3.6.7E MD.
Shall I upgrade to 3.4.0 and 15.0(1r)SG7 or go with the recommended 3.6.7E, If I do it, can I directly jump from ROM: 15.0(1r)SG2 to 15.0(1r)SG7 and from 3.2.0SG to 3.6.7E or there is middle steps. Is there any good posts to show how to do the upgrades
I really appreciate any helpful feedbacks or advice from your experiences.
