iWay Software has made every effort to ensure that iWay Service Manager (iSM) release 6.x is compatible with earlier releases. Overall, this effort has been successful. Specifically, all channels and process flows that were designed in earlier iSM releases (for example, 5.6 and 5.5) are expected to function properly in iSM release 6.x. The exception is any application that depends on timing or "bugs." Applications that follow best practices should port over to iSM release 6.x seamlessly.

The only major exception are the cases where applications rely on situations where strict adherence to RFC recommendations has not been applied.

Since iSM 6.x is a major release, many new features including improved performance and security are available. As a result, some incompatibilities may arise which can be handled by upgrading component configurations.

The iWay Migration extension provides tools to migrate an iSM 5.x release to a 6.x release including providers, special registers, schemas, and tools to compare IFL functions and XPaths.

For more information on the iWay Migration extension, see the iWay Service Manager Migration Guide for the 6.0.1 release.
