The procedure to upgrade the IOS in a 2500 is as described at http://www.cisco.com/en/US/partner/products/hw/iad/ps497/products_tech_note09186a0080110d2c.shtml.

For the 2600, refer to

http://www.cisco.com/en/US/partner/products/sw/iosswrel/ps1831/products_tech_note09186a00800f81f9.shtml

You could also refer to the technical documentation for more version specific upgrade details.
