Overlay Policy Data

The diagram following shows a SiteMinder policy domain named Domain1 in the source policy store that has to be exported and imported to the target policy store.

The target policy store already has a domain with the same name, but there are differences between the two:

• The properties of Realm1 have been updated in the source policy store and consequently have different values from their counterparts in the target policy store.
• There is a Realm2 in Domain1 that does not exist in the target policy store.

To specify a granular import where the target policy store is updated with the latest changes from the source policy store, the command line on export would look like this:

XPSExport gran-add.xml -xo-overlay CA.SM: :Domain@03-0fb7bd02-6986-4bb9-b240-c232358958b1 

After a successful import the properties of Realm1 on the target policy store are updated, as shown in the figure following.
