Can anybody advice if it is possible to upgrade firmware on Catalyst 2820 from version 5.34 to 9.x.
I have older type of 2820 Switch (WS-C2822). It is not WS-C2822-A and not WS-C2822-EN. It was manufactured on June 1997.
I have already file, but hesitate to do it. Version 5.34 doesn't have ability to upload existing image to TFTP server, and I am afraid to mess my switch.
I was looking at http://www.cisco.com/univercd/cc/td/doc/product/lan/28201900/
but it is confusing for me.
Please help.
