We have an upgrade to an application coming up which requires a site collection to be deleted and recreated. In terms of managing the existing users experience during upgrade what would be the best practice for redirecting requests for that site collection to a holding/maintenance page?
If it is under the root managed path of a web application would you just change IIS settings to redirect to a different URL?
If it is under another managed path within the web application then how could this best be managed?
