Hi,@Nikhi
Some features have been redesigned in the new workspace. Here are the main differences.
1.Creating the new workspaces doesn't create Microsoft 365 groups like classic workspaces do. All the new workspace administration is in Power BI, not in Office 365. You can still manage user access to content through Microsoft 365 groups, if you want. You just add a Microsoft 365 group in the workspace access list.
2.Use more granular workspace roles for more flexible permissions management in the new workspaces. In classic workspaces, you can add only individuals to the members and admin lists.
3.Assign user groups to workspace roles: In the new workspaces, you can add multiple Active Directory security groups, distribution lists, or Microsoft 365 groups to these roles, for easier user management.
4.Contact list: In the new workspaces, you can specify who receives notification about workspace activity.
5.Create template apps: You can only create template apps in the new workspaces.
6.Share datasets: To share a dataset outside a specific workspace, you need to save the report that contains the dataset to one of the new workspaces. You can't share datasets from classic workspaces.
7.You can't create or consume organizational content packs in the new workspaces. Apps and template apps replace organizational content packs in the new workspaces.

Hope it helps.
