Corda and Corda Enterprise compatibility
Corda Enterprise Edition 4.0 guarantees the wire stability and compatibility baseline introduced in version 3.0 of the open-source release of Corda is maintained with future versions of Corda Enterprise.
Corda Enterprise Edition 4.0 can be used in mixed-version/mixed-distribution networks seamlessly transacting with nodes running on a minimum platform version of 4. See versioning for further information.
Corda Enterprise Edition 4.0 nodes can transact with nodes running Corda 4.0 and future versions, providing the CorDapp is compatible with and between platform versions and distributions.
CorDapps originally written for Corda 4.x are API compatible with Corda Enterprise Edition 4.0 and future versions. Developers can switch their IDE to Corda Enterprise Edition 4.0 without any code changes in their CorDapp.
The reverse is not true. We do not commit that CorDapps compiled against Corda Enterprise will run on Corda (open source).Corda Enterprise Edition 4.0 nodes can run, without recompilation, CorDapps developed on and packaged for Corda 4.x. However, owing to advanced features in Corda Enterprise, such as database migration scripting support, we anticipate application developers will build their CorDapp kernels (contracts, states) against Corda but supply separate Workflow Jars (that depend on the same kernel) that are optimised for the two distributions. See Separation of CorDapp contracts, flows and services for further information.
