Rational Synergy 7.1 supports DCM transfers to and from releases 6.4 SP1, 6.5 SP2, 6.5a, 6.6a, and 7.0. Patches to these releases are required for DCM compatibility. For additional information, see the Rational Synergy Readme for Release 7.1 and the product README files for patches to the earlier releases.
With these patches, DCM in Rational Synergy Release 7.1 is compatible with Rational Synergy Releases 6.4 and 6.5. To exchange data with releases before 6.4, you must do so through an intermediate database.
In general, when a transfer package is generated from a Rational Synergy Release 7.1 database, not all data and information can be processed in earlier releases. The additional data is ignored by prior releases. However, that also mean that only a subset of the data is represented in prior releases. Not all the 7.1 features and benefits are necessarily applied across a DCM cluster when some databases are at prior releases. To gain full benefit from Release 7.1, all the databases in a DCM cluster must be upgraded to 7.1.
Rational Synergy does not replicate processes or process rules from 7.1 to 6.4, nor does it replicate reconfigure templates or update templates from Release 6.4. If you used DCM to centrally administer update templates in earlier releases, you must upgrade all databases in the cluster to achieve the same effect with process rules in Release 7.1.
