Solution: I am able to do this with just a simple SQL Query and move wp-content/uploads folder directly to s3. No replace is required for updating link. Table of WP Offload Media Lite plugin used for linking 'wp_as3cf_items'

Query for linking Existing files to s3:

INSERT IGNORE INTO wp_as3cf_items (provider,region,bucket,path,original_path,is_private,source_type,source_id,source_path,original_source_path,extra_info,originator,is_verified) SELECT  'aws', 'us-_REGION_HERE', 'BUCKET_NAME_HERE', concat('wp-content/uploads/',SUBSTRING_INDEX(guid, 'wp-content/uploads/', -1) ) AS path, concat('wp-content/uploads/',SUBSTRING_INDEX(guid, 'wp-content/uploads/', -1)) AS original_path, 0, 'media-library', id as source_id, SUBSTRING_INDEX(guid, 'wp-content/uploads/', -1) AS source_path, SUBSTRING_INDEX(guid, 'wp-content/uploads/', -1) AS original_source_path, 'a:2:{s:13:"private_sizes";a:0:{}s:14:"private_prefix";s:0:"";}', 0, 1  FROM `wp_posts` WHERE `post_type` = 'attachment';

For Multisite, do this for each site with table prefix.

(Edit)

As you are using the free version so you have to manually upload all the existing files into AWS S3 then you need to run the following function to update the wp_as3cf_items table

function wh_syncWPMediaLiteTable() {
    global $wpdb;
    $wpUploadDir = rtrim(wp_get_upload_dir()[‘basedir’], ‘/’);
    $itemsTable = ‘as3cf_items’;
    $offloadSettings = get_option(‘tantan_wordpress_s3’);
    $lastAttachmentID = get_option(‘_site_transient_wh_last_sync_attachment’, 0);
    //print_r($offloadSettings);
    $objectPrefix = rtrim($offloadSettings[‘object-prefix’], ‘/’);
    $format = [
        ‘provider’ => ‘%s’,
        ‘region’ => ‘%s’,
        ‘bucket’ => ‘%s’,
        ‘path’ => ‘%s’,
        ‘original_path’ => ‘%s’,
        ‘is_private’ => ‘%d’,
        ‘source_type’ => ‘%s’,
        ‘source_id’ => ‘%d’,

        ‘original_source_path’ => ‘%s’,
        ‘extra_info’ => ‘%s’,
        ‘originator’ => ‘%d’,
        ‘is_verified’ => ‘%d’
    ];
    ksort($format);
    $format = array_values($format);
    #Getting the list of attachments
    $sql = $wpdb->prepare("SELECT p.`ID`,
                            MAX(CASE WHEN pm.meta_key = ‘_wp_attached_file’ THEN pm.meta_value END ) as ‘attached_file’,
