Upgrading 5510 and 5520 stacks 1

[lavrunin]

I just wanted to verify, before doing an upgrade to the switches the following;
I can upgrade the diag and img files in any order and should reset after each upload
and If I upgrade the base of the stack that all the devices in the stack will be upgraded.
Thanks,

If they are stacked together, then yes, all units would be upgraded at the same time. You'd upgrade the diags version first, then the image.

You may need to do a two step update, depending on what release you are on today and what release you are going to be upgrading to. The switches will automatically reboot after the diag and software update.

As always, get a config backup before you upgrade, assuming you have multiple VLANs configured on the stack.
