HI Ahmad,

as per release nots of 7,5 version:

you can not direcly upgrade from 6.0.199.0 to 7.5.

First you need to pufarde to 7.0 or higher then you can go direcly to 7.5

Just to add..... You might want to consider going with v7.4.110.0 MR1 or v7.4.121.0 MR2 for stability.  If you need to go to v7.5, only do so because of features.

Thanks,

Scott

Upgrade Software Version WLC 5508

addition to Sandeep & Scotts feedback,

When you do the upgrade, make sure your 5508 FUS also get upgraded to latest version 1.9.0.0. Here is the release notes for that

https://www.cisco.com/en/US/docs/wireless/controller/release/notes/fus_rn_OL-31390-01.pdf

This process will take 30-40min & do this within a sufficient outage/maintenance window.

Here is the release notes for 7.4.121.0(7.4MR2) the one I would recommend

http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn74mr02.html

Also refer the compatibillity matrix to see which product it will support depending on the products that are available at your environment
