Comparing Customizing Themes
To help you address upgrading and custom themes, beginning in SP 10 a Theme Diff Tool is available. This tool compares two themes "in place" on your Blackboard Learn server. You can also run the tool on a machine without Blackboard installed, comparing two themes, either zipped or expanded that you have downloaded from your Learn instance. The Theme DIFF Tool is available from Edugarage.
For more information about customizing Blackboard themes, see the Themes Showcase on Edugarage.
