Install two instances on same server

Hi there,

I have a license for WHMCS. I currently have version 5.2.16 but would like to update to the latest version (5.3.5)

However, I have made extensive customizations to my current version. So I want to do a clean install of version 5.2.16 in another folder on my server and compare with my working version. Is this allowed?

Thanks.
