Hi Mike,

 

 

You don't actually need an active support contract to upgrade units. Roughly speaking, you can upgrade to the version which was available at the time you last had support. You can get the list of versions/dates from SOL7727:

 

 

http://support.f5.com/kb/en-us/solutions/public/7000/700/sol7727.html

 

 

So if you had support as of 2009-11-24, you could actually install any current release. You can reactivate the license from the GUI and see the service check date in the new bigip.license file.

 

 

If you do want to downgrade from v10.x to 9.3, you could reinstall 9.3 from scratch. The license for 10.x should still work for 9.x.
