Existing drivers that were created for DirXML® 1.1a continue to run with Identity Manager.
The Metadirectory engine that ships with Identity Manager 3.5.1 is backward compatible with older drivers as long as the older driver shims and configurations have been updated with all the latest product updates and patches. Because the engine is backward compatible, you can run DirXML 1.1a drivers on the Identity Manager servers as long as you want to, without making any changes to them.
However, the iManager plug-ins have only limited backward compatibility. Older drivers can be viewed in the Overview of a driver set, but the driver configuration can’t be viewed or edited without converting the driver. When you click a DirXML 1.1a driver in the Driver Set Overview, the Identity Manager plug-ins discover that the driver is in DirXML 1.1a format, and prompt you to convert the driver to 3.5 format using a wizard.
If you don’t want to make any changes to an existing driver yet, you can cancel out of the wizard.
To edit a 1.1a driver in 1.1a format, you must use the DirXML 1.1a plug-ins. To do this, you must use a separate iManager Web server with the 1.1a plug-ins installed on it. You can’t use the Identity Manager plug-ins that ship with Identity Manager to edit a driver configuration without converting the driver to Identity Manager 3.5.1 format.
