My Questions are:
1. Current ROM: 15.0(1r)SG14 so Do I need to upgrade the ROM also?
2. What is best way to upgrade the this IOS?
3. What is Downtime effect? Are both systems will reboot at the same time or will reboot the primary first and secondary will letter?
4. Any other things do I need to take care?
Thanks in advance.
