Can i just save the FUS update for a later time, and upgrade just the Product Version to 8.5.131?Ideally I would upgrade the FUS first, then move onto upgrading the PV, however I have a small window of time and was looking at breaking up the tasks.Two things, I would highly recommend that you upgrade from 8.0.133.0 to 8.3.141.0 then 8.5.131.0.
First, you will need to do is to download the Wireless IOS version 8.0.140.0 from the Cisco support site to your TFTP server. For controllers that do not have a FUS applied e.g. If deploying remotely– plan ahead and setup a local TFTP/FTP server for file transfers and place the software on a server local to the site to avoid firewalls and slow transfer speeds.4) If possible be ONSITE physically to monitor the device(s) Or at least have a local out of band terminal attached to console port.5) Attach a Serial console cable NOT mini USB to the Controller prior to FUS 1.7.0.06) Large Sites that are High Touch Five Nines 99999.% Work in pairs to upgrade and monitor the controllers and check the configuration and test after reboot.

Make sure to have a backout plan, your ITIL service manager will respect you more.
Depending on your current config, you're probably fine with this choice.
