I've found a way to fix 179,300 posts from prior to the site platform switchover. I've been toying around with this for a few days. Maybe pussying around is more like it since I'm taking so many precautionary steps to ensure it's accuracy done correctly.
The reason for the 'fix' is because all of those posts prior to May 18th, 2011 have lost their formatting. It's been bugging me for a very long time. Sure, we could just delete them, but that's over 5 years of 'history' that I don't want to simply be gone with. Therefore, I've spent hours coding, testing and working out a plan to restore the posts.
I've made a mirror of the current database and been running tests against it, then making it the live database for the site to see if things work. So far, so good, but there's a lot more work to be done yet.
I'm only mentioning this so when you see weird things on the site, it's expected, no worries, I have it under control.
No posts are expected to be lost during this event and hoping to have it completed within two weeks. That's the goal.
