Issue
I need to change the Salesforce user that Heroku Connect uses. Is it possible to do so without an interruption in syncing?
Resolution
Yes, re-authorizing your Salesforce user will not result in any extended downtime for your app. Please see the [Manage Salesforce])(https://devcenter.heroku.com/articles/heroku-connect#manage-salesforce) section of our Dev Center documentation for more information.
