Hi Praveen,
Unfortunately, we do not have an automatic integration.
However, GRLOADER in CMDB can use a JDBC data source pointing to the UIM database to get the device details from these tables:
These tables will have what you need:
CM_CONFIGURATION_ITEM
CM_DEVICE
While it is not an out of box feature to integrate the two, it should not take much time to get it working with CMDB's GRLoader.
Hope that helps!
