Comment 2 for bug 1815919

Thanks for the quick answer!

Yes, the backup file is there, as it's the one I used to confirm the issue by trying to upgrade again. I saved it to a separate folder for those additional tests, in order to be sure it wouldn't be lost, so good to know the data is still there.

With respect to your suggestion, it won't be easy. I've been keeping a diary with lifeograph pretty much every work day since 2011, so there's *A LOT* of pages: it would be very hard, if not impossible, to remove all entries except those that are deleted. I know many pages have been deleted because I noticed some missing patterns (e.g., events that I knew had 8 entries in a row with the same title, but now only have 4), but identifying them in ~2500 diary pages would be a titanic effort.

What I can do is try create a new small diary that only contains 4-5 of the pages that I know are not in the upgraded diary, and a few that are, and try to upgrade that one. In that case, it should end up with only the pages that remain in the original diary as well. Would that work and give you enough to work on?

If there's any investigation I can do myself, e.g., logging that happens somewhere during the upgrade process that I can look at to give a hand, please let me know.
