My website is ready on staging environment. I want to know how much time will it take to make the website live from the staging environment. Also tell me how to do that?
Hi @Taib_Bilal 
Welcome to the Kinsta Community!
To push a Staging environment to your Live environment, you’ll want to use the Push to Live function inside MyKinsta: WordPress Hosting - Staging Environments - Kinsta® Docs
This process is generally pretty quick, but it does depend on the size of the site being pushed to Live, so it’s difficult to give a firm answer. For small sites, I would generally estimate 10-15 minutes, but there should not be any downtime during the process.
Once the push completes, the new site information from Staging will be available at the domain for your Live environment.
