Just take the hydrogen folder and zip it and try to install it on the other joomla with gantry 5 ...
Good info. That worked, mostly. The new Gantry 5 then saw the original Hydrogen template.
One more step was required in order to see the customized template style.
In the old site mysq tbl_template_styles, I found the name of my customized template style and exported that mysql row. Then, I imported that mysql row into the new site.
I'm thinking that when Joomla installs a new template, the installation file probably makes an entry into the mysql database. I was hoping to get the template installation file to also include the mysql entry for the customized template style.
