Hi all!!!
I have a core of 8 x 3750-X stack running IOS 12.2(55)SE4 and was wondering if I can do a straight upgrade to IOS 15.2 or there is a need for a hop upgrade?
A quick answer would be greatly appreciated!
Thank you!

I havent performed the upgrade with ths major release.
But checking at the release notes I can see upgrading to 15.2 the min software version is 12.2(55)SE5.
Please check the link below:

Hi,
I would advise you to upgrade to c3750e-universalk9-mz.122-55.SE10 instead of taking new train, and I have tested its supporting all NAC/ISE Features, IOS (c3750e-universalk9-mz.122-55.SE5) has some limitation for the 802.1x authentication.
Please follow the procedure for upgrade:
