# Salesforce Compatibility Considerations for Salesforce Connect—Cross-Org Adapter

Some Salesforce features and functionality have special behaviors or aren’t available for external objects that are associated with an external data source of type `Salesforce Connect: Cross-Org`.

- The cross-org adapter for Salesforce Connect can access only queryable objects in the provider org. If you define an external object whose table name specifies an object that can’t be queried, your users and the Lightning Platform can’t access that external object.
- You can’t use Salesforce Connect external objects to access big objects in another org.
- When you deploy an external data source that uses OAuth 2.0 from a sandbox org to a production org, you must update the authentication provider. On a production org, an external data source can’t use an authentication provider that directs authorization or token requests to a sandbox org. Similarly, on a sandbox org, an external data source can’t use an authentication provider that directs authorization or token requests to a production org.

Also review the considerations that apply to all Salesforce Connect adapters.
