<p>What tools would you recommend for setting up CI for build and deployment of multiple websites built on DotNetNuke using SVN for source control? </p>

<p>We are currently looking at configuring Cruise Control to work with NAnt, NUnit, NCover and Trac as a test case. What other combinations would worth investigating?</p>

<p>We have full control of our development environment so using some form of CI is certain here but I would also like to convince our production services team that they can reliably deploy to the system test, uat and even production environments using these tools.</p>

I would have a look at Team City

I know some people who are looking in to this and they say good things about it.
My companies build process is done in FinalBuilder so I'm going to be looking at their server soon.
CC is quite good in that you can have one CC server monitor another CC server so you could set up stuff like - when a build completes on your build server, your test server would wake up, boot up a virtual machine and deploy your application.  Stuff like that.
