Upgrade Two Joomla Sites

I need both of my travel-related sites—baasreizen.nl and beyondthefun.com—migrated from Joomla 5.4.10 to the latest stable Joomla 6 release. I already hold full administrator rights, hosting control-panel access, and recent backups, so you can start immediately without waiting on credentials...
