I'm beta-testing a financial management application for the Mac. The instructions clearly said "You should continue to maintain data in the last production version, as well as in the beta version, as data files may not transfer from beta to beta." (or words to that effect).
Now, I'd been a beta-tester for this application before. Several times. In years of testing it, I never had a data-file that wouldn't migrate itself from gold->beta->beta->new_gold quite easily.
So I stopped actually keeping data up-to-date in the old "gold" version. Why bother, right?
Wrong.
Installed Beta3 today. It refuses to read the Beta2 file.
Looks like I've now got to recreate the last two months of transactions. Oh, and since I installed Beta2 on top of Beta3, I need to find a copy of Beta2 somewhere so I can read the data and recreate it accurately.
Can you say "Ugh"?
Can you say "Excel"? How about "Paper & Pencil"?
