Install Fresh version of Website

Hi,
We have tried and tested so many plugins and recreated the website a few times and I would like to start a fresh install using only the plugins I plan to move forward with. I need to bring in users but they will have different roles as I plan to use only ToolSet User management and eliminate Ultimate Member Plugin. I'm with Siteground as a host and maybe they have a process for this also, but I definitely need some guidance.
Thanks
