Move folder automatically

Hello,

I have a shared folder called Commercial.

Inside this folder I have:
Customer A
-2010
-2011
-20xx
-2019
Customer B
-2010
-2011
-20xx
-2019
Customer C
-20xx
Customer …
-20xx

250 customers…

I intend to create a folder called Commercial and move all Customers there and only with the folders of the years until 2018 and keep the share folder only with those of 2019.

What is the best way to do this?
Manually it is very complicated.

Thanks
