http > https - Should Google Analytics be updated?

[simonmlewis]

We are looking to upgrade a site form http to https. It's a Wordpress site and we will use Let's Encrypt to do it.

Updating it takes very little time, and we are told we need to Add a Property to Webmasters and add the new sitemap.

But in Google Analytics (GA), do I need to go to the property and change the http dropdown to https, or will GA do it automatically as it reindexes the site?

Thanks.
