Finalize IONOS CMS Migration

I have already copied most of the data from my old server to a new IONOS VPS, but I need a knowledgeable hand to finish the job and make sure everything runs smoothly. The sites involved are built on WordPress, Joomla, and a smaller Moodle instance... (Budget: $30 - $250 USD, Jobs: DNS, Joomla, Moodle, MySQL, Nginx, PHP, VPS, WordPress)
