TC Upgrade error 6.5.5 to 7.0.3 with SQLServer external database

Hi,

I'm trying to run an upgrade of TC from 6.5.5 to 7.0.3 on a test machine before making the upgrade on our production machine.

We currently have 6.5.5 installed and is working with an external database which is SQLServer 2008R2.

I have taken a backup of the database and the data and installed the same version 6.5.5 on the test machine from the back up. This comes up fine as expected and I see all the configurations etc as per the production machine the only differnce being on the test machine i have SQLServer 2012. All good.

I then perform the upgrade by running the installer 7.0.3 and after the new version is installed i see the upgrade begin in the web interface. I get prompted in the web interface about the details and then proceed with the upgrade at which point it fails with the an error

Unexpected exception SQLServerException: SQL error when doing: Querying for a single value SQL query: select count(*) from trace_xe_action_map SQL exception: Invalid object name 'trace_xe_action_map'.

I don't see this entityin the database either before the upgrade or after the upgrade falls over.

Please can you help? I've also attached the server log.

Thanks
Doug
