Forward Compatible Replication (FCR)

Overview

The Delphix Continuous Data Engine supports the ability to replicate to a Delphix Target Engine running on a higher version. To do so, FCR has a few requirements and restrictions to consider:

• FCR is supported for replication jobs starting from a source engine running 5.3.0.0 and beyond.

• The target engine must be running 5.3.3.0 and beyond.

• As of 6.0.10.0, the FCR replication operation can not go beyond engine versions released more than 12 months apart. 

• FCR supports replicating between major versions as long as those specific versions are no more than a year apart.

Examples of supported and not supported FCR configurations:

Supported

• 6.0.3.0 to 6.0.3.0 (same version)

• 6.0.3.1 to 6.0.3.1 (same version)

• 6.0.3.0 to 6.0.3.1 (higher patch version)

• 6.0.3.1 to 6.0.5.0

• 6.0.3.0 to 6.0.9.0

• 6.0.4.0 to 6.0.10.0

Not supported

• 5.2.5.0 to 6.4.0.0 (source version not compatible with FCR)

• 5.3.0.0 to 5.3.2.0 (target version not compatible with FCR)

• 6.0.9.0 to 6.0.8.0 (source version higher than the target)

• 6.0.0.0 to 6.0.10.0 (there is more than a year between release dates for those versions)

Exceptions

Some of the newer versions of 5.3.x are not compatible with the early versions of 6.0.x.0 (6.0.0.0 and 6.0.1.0).

• 5.3.7.0 and 5.3.7.1 are not compatible with 6.0.0.0

• 5.3.8.0 and 5.3.8.1 are not compatible with 6.0.0.0

• 5.3.9.0 is not compatible with 6.0.0.0

• 5.3.9.0 is not compatible with 6.0.1.0 and 6.0.1.1

Replication matrix

The following table lists all the Delphix Engine versions that a user can replicate to the required or the latest version. 

When replicating from X.Y.X.* to X.Y.Z.* the target version has to be greater than or equal to the source version. The * convention is used to refer to patch releases and reduce the table size.
