Converting a Classic Sharepoint Hub to a Modern Hub

[BDaniel1015]

Hi there,

Our organization has a dated SharePoint hub that still uses the Classic Sharepoint interface and appearance. Interestingly, new pages and subsites that are created immediately assume the Modern appearance.

We'd like to adapt our Classic hub site (that is, our site that all employees are directed to, located at https://ORGANIZATION-NAME.sharepoint.com) to the Modern look. Whether this means creating it from scratch or doing some conversion, I wanted to ask for some guidance.

If we convert:

• What happens to pages and document libraries that were created using Sharepoint classic? Are these converted, too? Are they lost?
• How do we convert the site?
  • We have seen information such as 'connect to a Microsoft365 Team to convert to modern,' but we do not see this button anywhere. Our site is already connected to a Microsoft365 Team.
• We have a custom theme that was built into Sharepoint classic. What happens to this theme if we convert to modern? Is it lost, does it need to be recreated?

If we create a new site:

• How do we assign our Sharepoint hub url (that is, the URL https://ORGANIZATION-NAME.sharepoint.com) to the new site we create?
• How do we make the new hub site the "parent" to subsites?

Thank you all!

That article and the links contained within it I think will answer most of your questions. But if there are additional details to share to clarify this situation that would be helpful.

This article will be helpful for the last couple of questions: https://learn.microsoft.com/en-us/sharepoint/planning-hub-sites
