This was from the word doc, details and dates may not be 100% accurate. Was this part of why Apex decided to nuke our database? If so, link to that event.

Jon finally got around to importing the old co_block database from the SQLite from before apex. At first Jon had a slight heart attack when all they could find was some malformed databases as downloading the files didn’t work originally. Eventually it was found, and a program was made (https://github.com/GreenJon902/coreProtectDatabaseMerger), which then on this day the server was shut for like 3 hours while a backup was taken, debugging was done and then the database was converted and uploaded. Tho coreprotect for some reason sorts by row id and not date when using /co I which then had to be fixed as events did not order correctly for very old blocks.
