Hello Team,
We are planning to upgrade controller code as per below.
7.6.120.0 to 8.5.151.0.
7.0.220.0 to 8.3.150.0
8.2.121.0 to 8.5.151.0.
WLC model - 2504
I checked release note of 8.5.151.0. But there is no suggestion how to upgrade from 7.6.120.0 to 8.5.151.0.
Could you please advise how to proceed for these code up-gradation.
Thanks

You can also step upgrade 8.0 / 8.3 / 8.5
or You can upgrade to 8.5 straight, make sure also consider suggested to consider doing a FUS upgrade first, that's like a BIOS update and fixes a few very specific issues for code > 8.0.
Also, check the AP compatibility in release notes before upgrading.

I do not believe there is a procedure document available for you to refer.
instead, you can refer the release notes upgrade path and upgrade each level. (Note: always do the backup and do the upgrade in a maintenance window, if it in HA, check the HA requirements.)
here is shared one :
