Hi,

I’ve designed a 4-layer PCB in Altium and it’s designed well, but now I want to make some changes to the layer stack and routing.
Before I do that, I’d like to preserve the current version for reference.

So my question is:
Should I copy the entire project and work on that, or is there a way to duplicate just the PCB document within the same project so I can make changes separately and both pcb doc files will be in the same project?

Thanks in advance!

There is a big difference in "*preserve the current version*" and "*make changes separately*".
My advise is to always make a backup copy (Project / Project Packager) when you 'release'. That way you can always go back to that version without it being accidentally changed.
As for the possibility to have multiple PCB in a project - yes, that is possible.
Another solution is to store each (release) version of the project in a separate folder. This allows you to browse it in Altium too.

I would just create a new directory (you can name it as a new version), copy the whole project there and continue from there.

In additional to Robert's comment, have a version numbering scheme.
I use a letter for the PCB (layout), a number for the components (BoM) and another number for documentation (changes).
New directory generally is only needed for a new PCB layout.
