DirectAdmin Guides, Scripts and Tools
CustomBuild, SSL, email, backups, migrations and the da command line for DirectAdmin servers, tested on our DirectAdmin lab.
Short answer: This is the srvScripts hub for DirectAdmin admins: CustomBuild and PHP versions, SSL for domains and the hostname, Exim and Dovecot email, backups and restores, migrations from cPanel or another DirectAdmin server, and the da command line. Pick the section that matches the job.
Each page says how it was tested; many were run on our DirectAdmin lab server (DirectAdmin 1.712 on AlmaLinux 9.8), the rest were checked against the official documentation.
