So I'm looking at updating the IOS. &nbsp;This is an old switch: 3500XL version 12.0(5.3)WC(1)<br />
I have not yet update an IOS, so bear with me please.<br />
The migration path seems to point to 12.0(5)WC7 as the last /maintenance release.<br />
Can I go straight from (5.3)WC(1) to WC7?<br />
**What IOS image should I use and where is it?** &nbsp; &nbsp; &nbsp;

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
