Hi All
I have in the process of upgrading all my switches to the latest recommend version by JTAC and I have 4 EX4550 virtual chassis running 12.3R releases, can I upgrade these virtual chassis straight to version 15.1 which is the recommend version by JTAC. Does not matter if I can't use NSSU as I have performed upgrades not using NSSU.
Only asking as I was looking through the release notes for version 15.1 and it says you can not upgrade/downgrade more than 3 major version releases unless you are going from EEOL to and EEOL. The plan will be to upgrade all the EX4550 VC's to 15.1R6-S2.
Sorry if this has already been answered by another post.
