We released our joomla 6 templates, you can find them here:

Upgrade from joomla 5 to 6

First read the official instructions of this upgrade by clicking here (hopefully it will be there).  Then these are my template related instructions if you use our joomla 5 template:

  1. Does your server satisfy the joomla 6 technical requirements?
  2. Are your joomla extensions compatible with joomla 6? If yes, then:
  3. backup
  4. save your old template and its user.css file
  5. update extensions
  6. update to joomla 5.x
  7. set cassiopeia default
  8. Joomla Update/Options/Update channel: set Joomla next
  9. Pre-update check
  10. update to joomla 6
  11. set error reporting to maximum, and check the site for errors
  12. install the new joomla 6 template and set it default, it will overwrite the old template, but keeps the template parameters
  13. if you had a user.css, create a child template, upload the user.css into its css folder
  14. clear cache everywhere
  15. test
  16. set error reporting to default
  17. backup
