Hi Team, We are migrating our fnms 2019 R2, on our stage and prod environment from OS 2012 to OS 2019 on app server, beacon and db server. We are retaining the same IP address and hostname for the OS 2019 as of OS 2012. While we did that on stage, we can able successfully migrate to OS 2019 but the site was not resolving to the Alias name which we have on the IIS Bindings. We removed the bindings on old server and configured it on the new one. The site was accessible only through server name and IP address. Can any one suggest on how we can solve the issue.
Also any thing else we need to consider while doing the similar migration in Prod?
