When you upgrade zen 6.x-1.x to 6.x-2.x some of the region names change.
If you are using the Context module, this will break contexts that add blocks to these regions.
This code snipped can be used to update the contexts to use the new region names.
It is for context 6.x-3.x.
Note that this will help in any situation where your theme regions change or you change themes. It doesn't have to just be for zen upgrades.
The easiest way to run this is to install the Devel module and go to the Execute PHP code page (/devel/php), then paste this code (without the PHP tags) in the text area and submit.
Make sure you back up your database first in case anything goes wrong and you have to revert.
