Migration help from existing Gateway

Via WordPress.org:

I have Woo Subscriptions – https://woocommerce.com/products/woocommerce-subscriptions/ – on several sites and I’m interested in switching to StellarPay. The key issue is — I don’t want to lose any of my existing subscriptions.

So, can StellarPay import the existing subscriptions? Or would switching cause the loss of all current subscriptions?
