hey all, current switches in stack are non-E version (WS-C3750G-24TS) and running c3750-advipservicesk9-mz.122-44.SE2.bin. We're adding E version switches (WS-C3750E-24TD) to the stack. We should be ok as long as all switches are running 12.2(44)SE2? The reason we ask is that the E version switches are running this "universal" image (c3750e-universalk9-tar.122-44.SE2.tar). should we leave the E version switches on this universal image or upgrade them to the non-E image? Thanks for the help.
