Legacy modules are deprecated payment gateway, domain registrar, server and provisioning, addon, fraud, and support modules that WHMCS no longer maintains or distributes. This page describes the inspection process, the deletion and notification logic for modules that are in use, successfully deleted, or that fail to delete (including the log messages the system records and the notifications it sends to admins), and links to the manual removal steps for each module type. It also explains why a configured deprecated module remains active after an update because its stored configuration is not removed, and how to migrate to a supported alternative and then manually delete the leftover module files.https://docs.whmcs.com/9-1/system/updates/update-tutorials/check-for-updates/Mon, 01 Jan 0001 00:00:00 +0000https://docs.whmcs.com/9-1/system/updates/update-tutorials/check-for-updates/Gives the steps to manually check for a new WHMCS version by clicking Check Now on the Update WHMCS page, and what the An update is available message indicates about the current Update Channel and system requirements.https://docs.whmcs.com/9-1/system/updates/update-tutorials/prepare-to-update-whmcs/Mon, 01 Jan 0001 00:00:00 +0000https://docs.whmcs.com/9-1/system/updates/update-tutorials/prepare-to-update-whmcs/Lists the recommended pre-update checklist for self-hosted WHMCS installations: reviewing release notes for the target and intermediate versions, checking system requirements, protecting custom themes and order form templates with dedicated directories or override files, testing updates in a non-production environment, backing up the database and directory, and confirming MySQL permissions.https://docs.whmcs.com/9-1/system/updates/update-tutorials/schedule-automatic-updates/Mon, 01 Jan 0001 00:00:00 +0000https://docs.whmcs.com/9-1/system/updates/update-tutorials/schedule-automatic-updates/Gives the steps to enable Apply Automatic Updates and set the frequency, day, and time under Configure Update Settings on the Update WHMCS page.https://docs.whmcs.com/9-1/system/updates/update-tutorials/set-a-maintenance-message/Mon, 01 Jan 0001 00:00:00 +0000https://docs.whmcs.com/9-1/system/updates/update-tutorials/set-a-maintenance-message/Gives the steps to enter a Maintenance Message under Configure Update Settings on the Update WHMCS page, noting the Modify Update Configuration admin role permission required.https://docs.whmcs.com/9-1/system/updates/update-tutorials/set-the-temporary-update-path/Mon, 01 Jan 0001 00:00:00 +0000https://docs.whmcs.com/9-1/system/updates/update-tutorials/set-the-temporary-update-path/Gives the steps to create a writeable directory outside the document root and enter its absolute path in Temporary Path under Configure Update Settings on the Update WHMCS page.https://docs.whmcs.com/9-1/system/updates/update-tutorials/set-the-update-channel/Mon, 01 Jan 0001 00:00:00 +0000https://docs.whmcs.com/9-1/system/updates/update-tutorials/set-the-update-channel/Gives the steps to select an Update Channel value under Configure Update Settings on the Update WHMCS page, recommending Stable for most installations.https://docs.whmcs.com/9-1/system/updates/update-tutorials/update-in-the-browser/Mon, 01 Jan 0001 00:00:00 +0000https://docs.whmcs.com/9-1/system/updates/update-tutorials/update-in-the-browser/Walks through downloading and unzipping release files, renaming a customized admin directory, and running install/install.php in the browser for Full Release updates (upload, agree, backup confirmation, upgrade, delete install directory) versus the simpler Patch Set upload-and-visit-Admin-Area process.https://docs.whmcs.com/9-1/system/updates/update-tutorials/update-on-the-command-line/Mon, 01 Jan 0001 00:00:00 +0000https://docs.whmcs.com/9-1/system/updates/update-tutorials/update-on-the-command-line/Gives the cp -R command to move staged release files into the installation folder and the php -f install/bin/installer.php – -u command to run the update script, plus the rm -r command to delete the install directory afterward.https://docs.whmcs.com/9-1/system/updates/update-tutorials/update-with-the-automatic-updater/Mon, 01 Jan 0001 00:00:00 +0000https://docs.whmcs.com/9-1/system/updates/update-tutorials/update-with-the-automatic-updater/Lists the PHP requirements (128 MB memory limit, 250 MB disk space, allow_url_fopen, max_execution_time of 60+, Zip extension or proc_open, disabled open_basedir) and walks through clicking Update Now, downloading a database backup, reviewing customized files, and clicking Begin Update on the Update WHMCS page.
