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)
https://software.cisco.com/download/home/282600534/type/280926587/release/8.3.150.0

currently you are running:
Bootloder version: 1.0.1
FIRV: 6.0.102.0

onc you upgrade to FUS version 1.9 you will see....like this
* Field Recovery Image is upgraded from 6.0.102.0 to 7.6.101.1
* Bootloader is upgraded to 1.0.20
* Offline Field Diagnostics is upgraded from 0.9.28 to 0.9.35

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