Impact of SSL update of Zuora on Salesforce Integration

[nayanbehera]

Our current Salesforce application is rest based callout to Zuora , we also use Zuora 360 degree sync to sync billing account and subscriptions to Salesforce. Will there be any impact on Salesforce Integration because of Zuora updating the SSL certificate from Symantec to Comodo, Digicert, or AWS issued certificates. 

Could you please help with below questions : 

1. What will be the impact on integration with Salesforce?
2. Will the Zuora public key going to change ?
3. Will there be any change in existing Zuora callout endpoints after the update?
