    I have some older themes that are used in a multisite instance (Crystal and Expose, for example).

    They break when I update to the most recent version of Genesis (currently 3.0.3) so I had to go back a couple of versions (2.9.1).

    In order for the old ones to keep working, but me to be able to use new themes with the new version of Genesis, can I have two versions of the theme running at the same time?

    The idea would be to simply change the code in the older themes to reference a folder called "genesis-2.9.1" with the older version in it.

    Template: genesis-2.9.1

    Thoughts?

    You are correct. Genesis 3.x no longer supports XHTML themes.

    I think you may have a problem at the PHP level if you proceed with your plan. Many of the function names in the two versions of Genesis will be the same. In PHP, function names have to be unique across the entire system and the re-declaration of a function name isn't permitted. It will cause a fatal error.

    Using namespaces will circumvent the potential for function name collisions, but Genesis doesn't use namespaces. You would have to modify every PHP file in the earlier version of Genesis to add a namespace. It's a lot of work, and probably a lot more than updating 2 themes to HTML5.

    Thanks.
    Any good resources you can point me to on properly updating those themes to HTML5?

    You would need to enable HTML5 on the site - https://my.studiopress.com/documentation/snippets/html5/enable-html5-markup/.

    But you would also need to convert all of the CSS to be HTML5 and not XHTML. And then probably your page templates. Cobaltapps has a converter at the bottom of this page. And you would need to also include new responsive CSS to those themes for them to be responsive. And, if you wanted to take advantage of the block editor, then you'd need to add that functionality to those themes.

    Genesis has come so far since XHTML that you would need to put those on a staging and try to convert them. It would probably be a better use of your time to just switch themes.
