2602 AP require min version of 7.2.100.0 and newer.

so you need to upgrade the WLC ftom 7.0 to 7.2 or higer.

Regarding issues:

1. you are uploading wrong files

if you newer AP models then you nee dto upgrade further.

upgrade path:

First you need to upgrade from 7.0 to 7.4 version
then upgrade to 7.4 to 8.0
8.0 to 8.3
and last 8.3 to 8.5
