Dear Members,

I need to upgrade 5508 from 7.6 to 8.3.xx. Do i need to upgrade FUS image latest to 1.9. Attached is the screenshot regarding the current SH SYSINFO command output.

Hi Kashif,

Cisco recommand to upgrade the FUS version to 1.9 specially if you want to run the 8.3 code on WLC.

https://software.cisco.com/download/home/282600534/type/284364857/release/1.9.0.0

Regarding Software upgrade: First you need to move from 7.6 to 8.0 version then to 8.3.150.0(Direct upgrade from 7.6 to 8.3.150.0 is not possible)

Dear Sandeep,

Thank you so much for your help. So it means i need upgrade the FUS image
first then upgrade the IOS.

[Sandeep Choudhary]

yes upgrdae FUS and then software. But make sure you take a downtime of 1 hour as FUS image alone will need 45 min.
