Before you download version 6.77 (or any older plugin version), understand the risks:
Recommendation: Use version 6.77 only for migrating to a newer WordPress installation. Once migrated, update the target site to the latest All-in-One WP Migration plugin and perform fresh backups with the modern version.
Even a legendary version has quirks. Here’s how to solve them: Before you download version 6
This is why professionals love Version 67 portable:
cd /var/www/html/wp-content/plugins/all-in-one-wp-migration-portable/
php cli.php restore --file=/home/user/backup.wpress --siteurl=http://localhost:8080
No web server, no database connection needed. It writes directly to wp-config.php. Recommendation: Use version 6
Fix: You may have downloaded the standard plugin by mistake. The portable version has a file named PORTABLE_README.txt inside the root folder. If not present, you have the wrong build.
After activating version 6.77, go to Plugins → Plugin File Editor (or check the plugin’s readme) – you should see: Even a legendary version has quirks
Version: 6.77
And the “Export/Import” screen will not show the “Upgrade to Unlimited” banner that appears in newer versions.
I understand you're looking for a specific older version (version 67) of the All-in-One WP Migration plugin, described as "portable." However, I need to provide some important clarifications and guidance before proceeding.
Fix: Open the portable constants.php and add:
define(‘AI1WM_MAX_EXECUTION_TIME’, 0);
