Today IIS team has made the URL Rewrite Module for IIS 7.0 Release To Web (RTW) available for download. This is a final, production-ready release that is officially supported by Microsoft.
Install the URL Rewrite Module for IIS 7.0 RTW today!
Microsoft…

1) It is better if you un-install CTP and then install Go Live release. When you un-install CTP, the rules in your web.config file will be preserved. If you had rules in applicationHost.config files those will be removed when you un-install, so I would recommend to back up the applicationHost.config in that case.

2) ARR module CTP works with the Go Live release or URL Rewrite Module.

1) Can I install it on top of the CTP version or should I uninstall it first? If so, will my rules be preserved?

2) Is ARR module working with this Go Live release? Or will the gold version of ARR be released any time soon?

Thanks,
Borek
