Test-SPContentDatabase Sharepoint 2013 upgrade

Hi,

I am upgrading from Sharepoint 2010 on Windows server 2008 to Sharepoint 2013 Windows server 2012,

When I run Test_spcontentdatabase I get this error,

Category        : MissingAssembly
Error           : True
UpgradeBlocking : False
Message         : Assembly [Microsoft.ReportingServices.SharePoint.UI.ServerPag
                  es, Version=10.50.0.0, Culture=neutral, PublicKeyToken=89845d

I have installed Reporting Service on the new server.

Where can I fix this? can I ignore this and continue with the upgrade?

thanks
