problems for subscription change

Good morning,

I need information,

we are changing the monthly to annual subscription, What can happen with this change?

we risk a double subscription? For previous subscriptions, will we receive a refund? Do you make a credit note?

Thanks

All the limitations of the silver plan are the same both on monthly and annual subscription. The only changes will be period and amount of the billing.

If you would like to change your subscription to Silver yearly, please cancel the current Silver monthly subscription directly from the Paypal site firstly.

How Can I Cancel My PayPal Subscription?

After that, you will be able to upgrade your account to Silver yearly without any double subscription risk.

->You can cancel your subscription, request refund for 8 days and downgrade your account immediately.

Or, you can cancel your subscription and schedule your account to downgrade to free on April 3rd, 2018. In this case, you can use your silver monthly subscription limits until April 3rd, 2018  before your account is downgraded to free as well. 

You need to upgrade your account again to the Silver yearly subscription both of these cases given above.
