If the flex field has the same name as the repeater and all the sub fields of the first layout are exactly the same as the old sub fields then you need to do something like this

// query all of the posts of the post type
$args = array(/* your query args here */);

$query = new WP_Query($args);
while ($query->have_posts()) {
  $query->the_post();
  // get the number of rows in the array
  $rows = get_post_meta($post->ID, 'repeater_field_name');
  // create an array containing the first layout $rows times
  $value = array_fill(0, $rows, 'first_layout_name');
  // update with the new value
  update_post_meta($post->ID, 'repeater_field_name', $value);
}

I think this would need to be done after changing the field type but before attempting to update any posts that use the field.

This can probably also be done with straight db queries, but I’m not sure how to do that.

As always, when making large changes to the database always back it up first.
