Will Creating a Teams Group from an existing Sharepoint Team Site increases the Site Storage to 25T?

Hello Everyone,

We have this existing Sharepoint Team Site that is used for file repository. Now the site is running out of storage and we are looking for another options on how we can add up storage to the existing site without additional cost before we conclude in purchasing the O365 Extra File Storage Add On.

I am aware that creating a Team from an existing Sharepoint Site or O365 group is possible but I am not quite sure if creating a Team from an existing Sharepoint Site will add up storage on that existing site - which I am hoping could also be 25TB.

Any helpful thoughts will be much appreciated.

Thank you
