Convert Office 365 classic team site template id (STS#0) to modern site template id (STS#3)

Question

In SharePoint Online, I have a classic team site. I know the steps to convert the look and feel to modern UI using modern site pages. However, the template id of the actual site i.e. "STS#0" is not changed.

Is there a way to convert the template id from "STS#0" to "STS#3" using PowerShell or any other method?

Thanks in advance.

Based on my research, you can not change site template of an existing SharePoint site, it is by design.

We suggest that you can go to the Microsoft Tech Community to submit a feedback.
