Did new forum software lose several weeks of recent posts??

Should be obvious to all, but it's apparent this forum's software platform has recently been changed.

As part of the migration it appears a forum thread database from several weeks ago was used for the conversion, rather than taking a most-current overnight backup and converting it.

Consequently all of the posts and responses to pre-existing threads, and all very new threads of the past 1-2 weeks, have all been lost.

Unfortunate. Seems like there might have been at least some advance mention of what was coming to the forum users, just to give us a heads-up. Also, it's really unfortunate that the most recent 1-2 weeks of forum content has simply disappeared.
