Is it possible to run two versions of Telerik Reports in 1 IIS site ? This is a legitimate request as a client has many pages using an older version of Telerik Reports and we want to use the latest version on our new pages. All of the pages are hosted within one IIS site. We can add both versions to the GAC, but there's a lot of Web.Config entries needed - what do we do with the versions there ?

Thanks for the reply. I should have probably been clearer in my question...
I know you can have 2 versions in the GAC, but Telerik Reporting relies on various settings in web.config. A couple of these settings specify the version to use. There is no way I can see that you can specify multiple rows.
e.g. this has the version hard-wired, so I don't see how its possible to have 2 versions of this handler in use ?
<add name="Telerik.ReportViewer.axd_*"
path="Telerik.ReportViewer.axd"
verb="*"
type="Telerik.ReportViewer.WebForms.HttpHandler, Telerik.ReportViewer.WebForms, Version=6.2.12.1017, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" preCondition="integratedMode" />

Hello Mark,
Our suggestion would be to restrain from such deployment setups and upgrade the old reports to the new version. The product offers and Upgrade Wizard to take care of updating all references and the viewer itself has not been modified for a while now, so you should not hit major problems. If you're going to use a version after Q2 2012, please review the Q2 2012 release notes and How to migrate your project to utilize the new ReportSource objects KB article.
All the best,
Steve

Hi Steve - not really the answer I hoped for. We use Reports for our application (DocRead) so have to configure it on the customers servers. However, in a few cases customers already use Telerik Reports themselves (for other internal use). We don't want to force them to upgrade, not do we want to test with a downstream version.
