Woocommerce Subscriptions Expert Needed

I recently migrated many WP sites to a WPMU network. The sites all have active users that have subscriptions (using the Woocommerce Subscriptions plugin) that auto recur. After migrating the original users, that were migrated, now no longer auto recur and go "on hold" whenever it's attempted even when their payment method is correct. New users are recurring correctly. The source of the issue may be that the WooCommerce version installed on the new WPMU is a newer version than the WooCommerce that was installed on the original servers. I am looking for a WooCommerce Subscription EXPERT. I have been working with a contractor to do the migration and neither of us have been able to figure it out. Only apply if you have experience fixing this sort of issue in the past.
