Is this possible? Migrate existing data storage to S3

sorry for the bother,

I added the exact:

  'objectstore' => array(
        'class' => 'OC\\Files\\ObjectStore\\S3',
        'arguments' => array(
                'bucket' => 'nextcloud',
                'autocreate' => true,
                'key'    => 'XXXXXXXXXXXX',
                'secret' => 'xxxxxxxxxxxxxxxxxx',               
                'use_ssl' => true,
                'region' => 'us-east-1',
		    ‘use_path_style’ => false,
        ),
  ),

before even creating the admin user, then after I did that, reset the apache sudo service apache2 restart then refreshed the page, and continued.

now it was obvious server didn’t take the S3 bucket since the bucket is empty, but the weird thing, when I opened the config.php again, I didn’t find S3 configuration anywhere (the part that I have added). could it be overwritten, or I just forgot to save? have you faced something like this?

thanks
