Impact of Opening Backup on Current Version?

In trying to solve a problem with repeating sequential projects, I’d like to open a really old backup of OF (2014) so that I can see how I set them up in the past.

I know it is possible (assuming the software functionality didn’t change), but I have not been able to find a solution.

If I open this old backup, will it clobber/harm/change my current version in any way?
