Can anyone please suggest?

Web Deploy is probably the best, it can do it server to server (ie live sync/migration) as well as allow you to generate a package that can then be installed in the other server:

http://www.iis.net/download/WebDeploy

It includes GUI (extends IIS Manager) as well as command line options, can do it over HTTPS or directly using the IIS configuration APIs. It supports moving configuration, content, GAC, DLLs, Database, Certificates, SSL settings and more.
