How to rename installation profile name in existing website in D8

I have installed Drupal 8 with a custom subprofile. 'my_custom_profile'.

Development of site is almost completed and we have added all the contents in the site.

In this stage how can I rename my installed subprofile name from 'my_custom_profile' to 'custom_profile'?

Is it possible to update DB entries manually for subprofile?

1. Edit this line in core.extentions.yml in your config directory to your new name
my_custom_profile: 1000

• Thanks for your answer. But in my current core.extentions.yml which is located in docroot\core\config\install\core.extentions.yml which contains only below code:  module: {} theme: {} profile: ''  – ARUN Oct 27 '17 at 1:38
• If you have setup config_sync directory in settings.php then try to do a drush cim -y it will import all your sites current configuration. After that look what your core.extentions.yml file is – user72672 Oct 27 '17 at 6:51
