migrating from ClearQuest to RTC

Hi,
I am trying migration from ClearQuest 7.1.2 to RTC 5.0.2. I would like to migrate some ClearQuest record fields along with attachment and links between different record types. I was able to migrate fields and attachments using ClearQuest importer but so far no success with links. I would appreciate if anyone has any pointers on how links can be migrated?
Thanks in advance!

If you haven't already done so, you might want to check this help topic: Migrating Rational ClearQuest records to work items and its child topics. From that topic: "For links between work items to be created, all of the linked records must be included in the file that you import. For example, if Record A is a duplicate of Record B, but Record B is not imported, the duplicate link is not created. Instead, a custom attribute that contains the duplicate information is created."
