Before upgrading your switch software, make sure that you have archived copies of the current Cisco 
IOS release and the Cisco IOS release to which you are upgrading. You should keep these archived 
images until you have upgraded all devices in the network to the new Cisco IOS image and until you 
have verified that the new Cisco IOS image works properly in your network.

Cisco routinely removes old Cisco IOS versions from Cisco.com. See Product Bulletin 2863 for more 
information:

You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a 
host by using the copy flash: tftp: privileged EXEC command. 

Although you can copy any file on the flash memory to the TFTP server, it is time consuming to copy 
all of the HTML files in the tar file. We recommend that you download the tar file from Cisco.com and 
archive it on an internal host in your network.
