Actually, both of them are in there. The TZDB doesn't remove old names.
However, if you ask for all zones in India, it will only show up with
the new name as the old one is listed for "backwards" reasons only:
$ php -r 'var_dump( DateTimeZone::listIdentifiers( DateTimeZone::PER_COUNTRY,
"IN" ) );'
array(1) {
[0] =>
string(12) "Asia/Kolkata"
}
