Replacing entire ToolBox

I would like to create, modify, test etc etc a toolbox on a standalone system without changing anything on the Toolbox that is being used by all the other users. In essence I want to start with a new toolbox, clean it up, modify it and make sure we are happy with the results and then replace the existing one with the new one.

We are on 2018 SP2 working on a PDM. The current toolbox is located on the PDM and everyones system points to it.

What's the best way to do this if possible and what problems will I run into?

Thanks,

Matt
