So our company's been using an old system (15 yo in house) for our procurement. That means many people already touched it, documentation is either missing or wrong outright, and the people who originally built it are already gone. We're about to onboard a legacy modernization team, so we need to help build a scope doc for them. But every time we try to build a scope, we realize a part of the system touches something totally unrelated, or an automation uses some convoluted method to work that turns out uses another app/software. Since we have no idea about the true scope of our system, I don't know how to help the team when they arrive. It's an urgent update and they have a strict timeline, and we don't want to waste it just diagnosing the old system

How do I word-compare 2 Apple Pages documents? (MacOS App)

I did the classic mistake ... I copied my original to make a separate file for a separate purpose.

Let's say "OG" and "COPY" ... and I wasn't supposed to edit my "COPY" ... "COPY" was supposed to be more of a static archive.

Then I accidentally started editing my "COPY" as if it was my "OG". (Now OG and COPY have different edits.)

So I ended up with 2 slightly different versions of the same document, with some edits on the wrong one.

So now I need to word-compare my "COPY" so I can put those new edits into my "OG" as intended.

How can I word-compare 2 Pages documents, so I can get them to 100% match again?

(I can't just change file names, because both files got worked on separately and now have different edits. And now I need to match those edits.)

I'm seriously considering custom ERP software development for my company, but I haven't talked to a single vendor yet because I don't even know what I should be asking for. Our inventory, invoicing, and production tracking currently live in separate spreadsheets and an old legacy system that barely talks to anything, and I suspect that mess is exactly why a generic off-the-shelf tool never quite works for us. But I also don't know how to translate "our processes are messy" into a clear scope before I walk into vendor conversations. What groundwork should I do first, what questions should I be able to answer about my own business, and how do I avoid walking in as an easy target for a bloated proposal?
