There is also a GeoCombine branch in the works: https://github.com/OpenGeoMetadata/GeoCombine/tree/121-migrate-to-aardvark

Right now scripts are being referenced in two places on the website:

• At the bottom of the upgrade guide
• The dedicated scripts and tools page

I'd recommend moving all scripts and tools to that dedicated page, and replacing the content on the upgrade guide with a link to that page.
