Comparing customized themes

The Theme Diff Tool helps you address upgrading custom themes. This tool compares two themes "in place" on your Blackboard Learn server using your theme handles. You can also run the tool on a server without Blackboard installed, comparing two themes (either zipped or expanded) that you have downloaded from your Learn instance.

The Theme Diff script is called and located in the blackboard/tools/admin directory. The script takes two theme zip files as inputs and outputs an html page detailing the differences.

The tool returns an error message when the packages that are compared have different package structures. The tool can still be used to compare two packages with the same structure, whether the structure is before SP 14 or after, as long as the structure is the same between packages.
