You want to update existing subscriptions so that their billing cycle is the same?

[proud breach]

yes

[jade shell]

Then you need to change the billing cycle by using this: https://stripe.com/docs/api/subscriptions/update#update_subscription-billing_cycle_anchor
But I recommend doing some tests in test mode to make sure everything works as expected. You can use Test Clocks for this https://stripe.com/docs/billing/testing/test-clocks
