I am moving everything from my current VPS (about 200GB) to a freshly-provisioned server and want the changeover to be invisible to end-users. Both machines run cPanel/WHM, so you will have root access on each to shuttle across every website file, database and email account. The workload in numbers: 6–10 Joomla sites, one Magento store and two Prestashop shops. While the files and mailboxes copy over, the databases need an extra step—on the new server I’m switching from MySQL to MariaDB. I need you to handle that conversion cleanly, test each site, and confirm that all CMS extensions, shopping-cart logic and cron jobs work exactly as before. Key tasks you will own: • Full account migrations through cPanel/WHM, adjusting DNS or A-records only when final testing passes • MariaDB deployment and data import without loss or corruption • Any necessary tweaks to php.ini or Apache/Nginx vhosts so every site loads on the correct PHP version • Post-migration validation for Joomla, Magento and Prestashop (front-end browsing, admin login, checkout, email sending) I’ll provide SSH keys, WHM credentials and a maintenance window. Please outline your experience with cPanel transfers and MariaDB upgrades, plus an estimated timeframe for the switchover and DNS propagation monitoring.
