@yourrfriend thanks for posting here. What @mikew mentioned should indeed work (`sudo` shouldn’t even be necessary in most cases). You could also try `php upgrade_v3.php -i`, which does the same as `--ignore-warnings` but might work for you. If you are really stuck, you could open `upgrade_v3.php` in your file editor and remove line 750 (marked below). This will prevent the script from stopping regardless of whether you are running it with or without the `--ignore-warnings` flag. The script will remove itself after the upgrade anyway, so you can safely edit it without introducing security risks. > ---

@dennisameling thank you for your answer. i did with the `--ignore-warnings`. Upgrade process went smoothly without any error and it took very short time with more than 2M contacts and lots of custom fields. Appreciate your help. ---
