Recently I worked on a scenario where after an application upgrade and before go live, we were looking to switch DNS for SSO enabled Sitecore Web Application.
There are few and simple steps to follow:
There will be 2 URLs (Live and Upgraded Application), let's say L and U
- From Site Definition configuration file, swap hostName and targetHostName values between L and U config files.
- Since we were using WSO2 for SSO authentication, and input request SAML settings were done in web.config, So just need to swap SAML setting values between L and U.
- Please connect with your WSO2 team mate for SSO Url updates, by adding new ACS Url to authenticate with SSO.
That's it. For us after above 3 changes - it worked.
