license staging

Hello team, After a number of years our website is far from clean. Parts of older websites are in it en the website is slow. we have a staging website where I want to rebuild te website from scratch. Therefore I need to clean the staging website and install elevatebiz pro and use again, Is this possible with the elevatebiz pro license, we have. I think I can rebuild the website within two weeks. Both websites are in the domein: www.toerfietsleusden.nl Kind regards Hans Hagmeijer
