How to update postmeta with ACF?

Hello!

I am deeply appreciative of ACF. ACF is my favorite plugin.
I have a worry about updating postmeta.
First I set a ACF date item with saving default “yymmdd”.
But now I want to use as MySQL date format “yy-mm-dd”, so I am trying to update that format.
I think I should use ACF update function to update postmeta manually, but I don’t know which function to be used.

Is this code OK?

function update_acf_manually() {
    var_dump('update_acf_manually');
    $args = array(
        'orderby' => array('ID' => 'ASC'),
        'post_type' => 'member',
        'posts_per_page' => '-1',
    );
    foreach (get_posts($args) as $post) {
        $pm = get_post_meta($post->ID,  'join_date', true);
        $Y = substr($pm, 0, 4);
        $m = substr($pm, 4, 2);
        $d = substr($pm, 6, 2);
        if ($Y && $m && $d) {
            var_dump("$Y-$m-$d");
            $pm = "$Y-$m-$d";
            //update_postmeta($post->ID, $pm);
        }
    }
}

Thanks!

I think I have to use update_field();

function update_acf_manually() {
    var_dump('update_acf_manually');
    $args = array(
        'orderby' => array('ID' => 'ASC'),
        'post_type' => 'member',
        'posts_per_page' => '-1',
    );
    foreach (get_posts($args) as $post) {
        $pm = get_post_meta($post->ID,  'join_date', true);
        $Y = substr($pm, 0, 4);
        $m = substr($pm, 4, 2);
        $d = substr($pm, 6, 2);
        if ($Y && $m && $d) {
            var_dump("$Y-$m-$d");
            $pm = "$Y-$m-$d";
            update_field('join_date', $pm, $post->ID);
        }
    }
}
