The migration is pretty straightforward, you should be able to see the JComment migrator option from the backend > Komento > Migrator > JComment if you have the JComment extension installed on the site.

Remember to make sure you have to do the full backup before running this migration.

Thank you, I did not find that hint concerning JComments in the docs!

Best regards

You can update your site backend and FTP access at https://stackideas.com/dashboard/site if you need help with the migration.
