Upgrading Cisco Catalyst 6509-E Switch

[ammartalal]

We need to upgrade our core switch (Catalyst 6509-E) which is having Supervisor Engine 720 (WS-SUP720-3B). Our current image is s72033-ipservicesk9_wan-mz.122-18.SXF11.bin & we don't know which image to choose know, and which image would be supported by our box.

Please let me know if any other information is needed.

Thank you in advance.

Sup720 train SXI and SXJ are considered the most stable of them all.

What is the difference between SXI & SXJ trains?
