Rational Synergy 7.2 supports DCM transfers to and from releases 7.0, 7.1, or 7.1a. Patches to 7.0 are required for DCM compatibility. For additional information, see the Rational Synergy Readme file for Release 7.2 and the product Readme files for patches to the earlier releases.
With these patches, DCM in Release 7.2 is compatible with Releases 7.0, 7.1, or 7.1a. To exchange data with releases before 7.0, you must do so through an intermediate database.
In general, when a transfer package is generated from a Release 7.2 database, not all data and information can be processed in earlier releases. The additional data is ignored by prior releases. However, that also means that only a subset of the data is represented in prior releases. Not all the Release 7.2 features and benefits are necessarily applied across a DCM cluster when some databases are at prior releases. To gain full benefit from Release 7.2, all of the databases in a DCM cluster must be upgraded to 7.2.
