Can I recover a sandbox once it is refreshed? Our partial sandbox was accidentally refreshed 15 days ago, and we lost some valued work from our sandbox. It was refreshed and was moved to a different instance eg. CS94 to CS77 after it was refreshed. Is there any possibility to recover the sandbox data from before it was refreshed? Is this a service Salesforce will perform?
