Is a Shared Workspace assigned just to new Business accounts or are the old ones converted as well?

[dflow]

I have read in this answer about the difference of Team Folder and Shared Workspace.
It is states that Shared Workspace is a newer feature.

I see that when I fetch https://api.dropboxapi.com/2/team/namespaces/list

I receive only one namespace with the team_folder tag:

"name": "MyCompanie's shared workspace"

".tag": "team_folder"

But what can I expect from old Business accounts, that existed before the Shared Workspace feature?

Have those accounts been converted to support this, or will they return the old structure without a shared workspace and where you could have lots of folders with team_folder tag?

Some but not all older teams have been migrated to use a team space, so some teams do not have a team space and will return multiple team folders in that list.

You can find information on using the different configurations via the API in the Team Files Guide.
