I have to upgrade several stacks of 3750 switches, the stacks are built with a mix of G and E models.
Reading through the documentation I see several articles describing the upgrade for a stack, but they all describe upgrading stacks consisting of the same type of switch, not a mix as I have.
I need to upgrade from 12.2.35 ipbase to 12.2.53 ipbaseK9. I tried this today on one stack and ended up with one of the switches attempting to run an incompatibale image, so it wont boot up.
I have had a look at several threads here on Netpro, and now think that I cannot use the archive commands, that I have to manually load each switch in turn is that correct?
I'm thinking of using a TFTP copy to download a copy of both E and G code onto one switch (The master??) then manually copying the correct image onto the appropriate switch in the stack, finally deleting the incorrect code on the master switch. However this does seem a long way of doing this, is there a quicker way?
I had also thought of breaking apart the stacks, making stacks of the same type, using the acrchive command to do the upgrade then rebuild the stack, not sure if that would be any quicker.
Its a new build project, so i'm not too concerned about loss of any existing configuration. I just want to get this done without killing anymore switches!
