Copy app files
⚠ The source instance and all its data will be permanently deleted after migration completes.
ⓘ Application files will be copied from the source instance, excluding AMP runtime directories (AMP_Logs, Backups, Licenses, Plugins, Webroot) and root-level files. Remote targets are supported via the AMP file transfer API. This may take some time for large instances. The operation can be cancelled.
