Hi Rajkanth, I've been watching this question for a while, and since no one has jumped in with an answer I thought I'd give it a shot to get you started (if you haven't already google'd yet). I'm a coredata (and iphone app development) newbie too, here are the resources that I used to get me started:

The Stanford iPhone App course: http://deimos3.apple.com/WebObjects/Core.woa/Feed/itunes.stanford.edu-dz.4331559337.04331559339 has a good CoreData aspect to it, as part of the Paparazi series of assignments.

with slides here: http://www.stanford.edu/class/cs193p/cgi-bin/drupal/downloads-2010-winter

As you probably know, the iPhone Developer space has a lot of tutorials and sample code here: http://developer.apple.com/iphone

And, this tutorial looks quite thorough: http://www.techotopia.com/index.php/An_iPhone_OS_Core_Data_Tutorial

I know I'm not answering your question (especially relating to Migration), and since you asked over a week ago you've probably google'd it yourself - but hopefully a couple of these resources help you out as they helped me.
