Q. will it effect my blog visitors
A. No if you use a redirect or meta refresh link ( redirecting your users from site A to site B )

Q. Will my blog be displayed as "abc.blogspot.com" or "xyz.com" in search engines.
A. Both, one blog don't replace the other

Q. What will be the effect on my blog interlinks
A. You will need to check that all your internal links are pointing to the right domain name.

Q. Shud i remove my blog "abc.blogspot.com" from webmaster tools and add "xyz.com"
A. Nop, add xyz.com to webmasters tools, but don't remove the other, as you may need to check all data from the other domain, to check any issues, especially since you are triyng to migrate from one domain name to other.

Q. Shud i change my blog name from "abc" to "xyz"
A. it will make more sense, but there is no need to that.

if i add both abc.blogspot.com and xyz.com in GWT, will there be any duplicate content issue???
