My site does not have a robots.txt. I am trying to move my old site from one domain to the other one. I created 301 redirect and repointed my old site to the new one. I am on dedicated IIS server which does 301 redirect, but now I am faced with 'supplemental index' and I would like Google to remove my site completely.
Can I place robots.txt file for two domains on my new server, how can this be done?
like if myolddomain.com then disallow else (newdomain) do the crawl excuse my ignorance
