How we can we migrate the profile setting of one org to the another profile in another org?

Hi Mohit,
You cannot send profile settings directly to another org. For this you have to choose the component and the profile simentaneously if you want that the particular profile for the component will be added automatically while sending it to another org.
For change set:-
1. Add ‘Change Set Components’.
2. From ‘Profile Settings For Included Components’ add profile for which you need the changes to be made.

For Ant Script:-
* In package.xml do like this..

<Package>
<types>
<members>Component</members>
<name>ComponentName</name>

<members>Profile</members>
<name>ProfileName</name>

</types>
<version>36.0</version>
</Package>

Thankyou
