# Does a sandbox refresh or renewal impact FinDock?

Yes. When you create a new sandbox or refresh your existing sandbox with FinDock, you should carefully check the FinDock configuration in the new org.

We recommended the following:

* Check that your payment extensions are set up as test environments (test account toggle on)
* Delete any production targets pointing to live endpoints. This includes ProcessingHub targets and merchant account settings in payment extensions.
* Check that a default Source Connector is selected and the Heart Beat Job is scheduled under [Core general settings](/docs/setup/configure-findock-core#configure-general-settings).
* Check that there is a successful (working) connection to [WebHub](/docs/setup/configure-webhub#connecting-to-webhub) and to [ProcessingHub](/docs/setup/configure-processinghub#connect-processinghub-and-salesforce).
* Make sure you have a [Chatter group for file exchanges](/docs/setup/configure-processinghub#configure-file-exchanges).


Keep in mind potentially sensitive customer and payment data (e.g. bank account numbers and credit card tokens from PSPs) when working with sandboxes.
