Blospot to custom domain

I have a blogspot blog and I'm planning to buy a custom domain. My problem is I have few subscriber in my feedburner, how can I redirect them to my new feed without losing any subscriber?

 

Go to Google Feedburner > Click on the Feed Name > Edit Feed Details.
There you'll have the option to change the Feed Source (Original Feed).

 

This is very simple

 

There is no need to redirect if you are using custom domain on same blogspot url... because your blogspot url automatically redirect to customer url ..

 

After you changed your custom domain, you'll automatic redirect to new custom domain. So, don't have to worry about it.

 

Thanks all of you for clarifying this problem of mine.
