Update teamviewer automatically with new license.

Hi Community and new to the community,

But i immediately have a question for it.

We just purchased a corporate license(finally) from the current premium license we have. We are on version 11 and with the new purchase, automatically get he latest version. So my first concern was, okay how am i going to upgrade and update all the previous versions i have installed on our machine. Luckily they are not much( +75 laptop) i started to think different scenarios but i always think the simplest way ever.

Is it possible to just tell the current installed version to automatically update by just pressing a button?

Or should i do it using a policy and apply the policy for every single machine in our inventory list? with the help of the following two policies: Check for new version(enabled and enforced) + Install new versions automatically(enabled and enforced)?
