Importing work items with multiple links using a CSV import

We are importing a large project from one server (RTC 2.0.0.2) onto another server (RTC 3.0.1). We are trying to ensure that the links between items are all built correctly.We are building the link columns manually since RTC 2.0.0.2 doesn't support exporting links.

As we have been testing this by EXPORTING work items from RTC 3.0.1, we have found that the RTC exporter only exports one work item link per category. For example if work item 123 blocks 124, 125 and 126, in the export file under blocks only #124 is listed. However, I can see that #123 is listed in depends on for 125 and 126 so technically it imports fine. The same thing happens for other items, no matter how many links there are in the item.

Since we are building our link columns manually, we are trying to determine if it is possible to have more than one link on a single field.

One option would be to put those additional links in a second file and import it so that it updates existing work items, but we are looking to see if there is a simpler solution.

Thanks
