Hi,
I have two 3750: one runs C3750-I5-M version 12.1(19)EA1c, and another runs C3750-I5K91-M version 12.2(20)SE1. I want to upgrade the one with 12.1(19)EA1c to
12.2(20)SE1, but I got "ERROR: Image family mismatch". How to solve this problem? Is this kind of upgrade even possible?Appreciate any help,
