If we want to move site from say xyz.com to xyz.org. What all things we need to do to make sure seo works fine.

I am doing something like

1. Point both xyz.com and xyz.org to same ip where my site is working

2. Use cannonical url to have xyz.org/* instead of xyz.com/*

3. Add site to webmaster and make a change request.

But problem is we are not able to 301 redirect from xyz.com to xyz.org as both are on same i/p and doing so is causing redirect loop and error.

How to fix this?

Please help.
