>Of course, depending on what types of reports you currently have, these could be small or non-issues, or they could be significant ones that would take weeks or even longer in developer time to come up with workarounds. If you have a large # of reports in CR, odds are decent that you're talking about a non-trivial development effort. There are different migration tools and services out there, though I haven't used them.

>If I were staring a desktop-based reporting solution today and could pick the tool, I'd probably still lean towards CR. If it were a browser-based solution, I'd definitely go with SSRS. SSRS also has server-based features to create report subscriptions (e.g. to email reports or export to PDF to specific recipients on a schedule, and generate a history log of the output). With SSRS you get closer integration to SQL Server and SharePoint (the latter won't be relevant if you're not using SharePoint).

Nicholas: I don't have search capabilities, but in the dotnet forum (I think) there is a thread on comparison between the two and I did a chart a few years ago (outdated now but it gets you started in how to research it). If you can search the forums you should find it.
