[Buildroot] Easy Upgrade Path?

[Dan Pattison]

Hello List:

I've been getting used to the buildroot development environment using 
2009.02-RC2 for ARM AT91SAM9g20-EK. I have made lots of changes and 
additions that suit our project (config files, packages, etc.) We have 
successfully compiled and included some of our own programs.

What is the recommended method to upgrade to the newest build 
environment so we don't have to re-do everything? Is this possible?

Best Regards,
Dan Pattison
