Buddypress copy xprofile fields to user meta on registration

Question

Am able to use the following function POST registration.

But would like to achieve same ON registration.

So just a visit to the edit profile tab triggers the function below.

function copyUserMeta() {
    global $current_user;
    get_currentuserinfo();
    $user_id = $current_user->ID;
    $firstname = xprofile_get_field_data( "First Name" ,$user_id);
    update_user_meta( $user_id, 'first_name',$firstname);
}
add_action('bp_before_profile_edit_content', 'copyUserMeta');`

So CHANGES to the profile fields are reflected in the usermeta.

But would like also to have the fields copied to usermeta ON registration.

Had been using successfully a solution shown at http://buddypress.org/support/topic/xprofile-vs-usermeta-syncing-problems/ (with add_action( 'wpmu_activate_user', 'synchro_wp_usermeta', 10, 3);), but for some reason it no longer functions.

A potential workaround could be on first login go/redirect to members/userxprofile/edit/group/1/, though I would prefer the straightforward copy profile fields to usermeta on registration.

There is also a function add_user_meta()?

Background:- can/will research, can/will follow instructions but quite limited at coding. At the moment doing this on local installs.

Ideas, potential solutions very very welcome?

On registration, a bp_core_signup_user action hook is fired, which pass a $usermeta array to the action functions, and that array contains all profile fields data that you can utilize to synchronize BP profile with WP profile data:

add_action('bp_core_signup_user', 'ad_user_signup_usermeta', 10, 5);
function ad_user_signup_usermeta($user_id, $user_login, $user_password, $user_email, $usermeta) {

    // you need to know the field_id of the "First Name" field
    // one way to find out what is the field_id of the "First Name" field:
    // echo '<pre>' . print_r($usermeta, 1) . '</pre>'; die();
    // if the field_id, for example, was "field_2":

    update_user_meta($user_id, 'first_name', $usermeta['field_2']);
}

add_user_meta() function will be called through update_user_meta() if meta_key was not found in the database. So you can just use update_user_meta() for almost all cases.
