Drupal, Joomla, And PrestaShop Migration Guide

Older CMS migrations succeed when the destination matches the application version closely enough to boot before upgrades begin. Migration Monkey lets users select older versions, then the analyzer checks install-folder markers and can warn when the selected app does not match the source folder.

Drupal notes

Check PHP version, composer-managed dependencies, private files path, trusted host settings, config sync, cron, cache tables, and database collation. For older Drupal, plan an intermediate upgrade if the destination PHP version is too new.

Joomla notes

Verify configuration.php, database prefix, tmp/log paths, PHP extensions, template compatibility, and administrator login. Clear cache and test SEF URLs after restore.

PrestaShop notes

PrestaShop moves need extra attention to image folders, cache, module compatibility, PHP version, database size, and payment/shipping modules. Test checkout before DNS cutover.

Old-version rule

When the source is very old, restore first on a compatible runtime, verify it boots, then upgrade in stages. A migration and an application upgrade are related but should not be treated as the same task.
