SSRS ReportingService2010 change embedded DataSource to shared DataSource

Question

I have SQL Server 2008 with SSRS installed on one server and SQL Server 2008 R2 with SSRS installed on a new server. I want to migrate 200+ reports as well as a few shared s

Answer 1

So I kept working with the SetItemReferences method and had a brilliant idea that ended up working. The final code I used is below:

List<ReportService2010.ItemReference> itemRefs = new List<ReportService2010.ItemReference>();
ReportService2010.DataSource[] itemDataSources = rs2010.GetItemDataSources(catItem.Path);

foreach (ReportService2010.DataSource itemDataSource in itemDataSources)
{
    ReportService2010.ItemReference itemRef = new ReportService2010.ItemReference();
    itemRef.Name = itemDataSource.Name;
    itemRef.Reference = "/Data Sources/TMS";
    itemRefs.Add(itemRef);
}

rs2010.SetItemReferences(catItem.Path, itemRefs.ToArray());

The problem was that I was not using the same DataSource name as what was found in the report .rdl file. I was able to determine what the name should be using the GetItemDataSources method. Since this method returns an array and may have more than one item in said array, I looped through it to create multiple ItemReferences if more than one existed though I doubt that happens very often if at all.
