WE WILL BE DOWN SUNDAY FOR THE MIGRATION.
I expect to shut the site down around 1pm ET. I have no ETA for its return. I expect just the data migration and conversion to take around 6 hours. After that, there's going to be some essential work just to get the new site running, and to make sure everything is intact.
I intend to bring the new site up as soon as possible. Meaning, while we're still working on it after the data is moved. So Sunday night, expect it to be shut down periodically, expect wholesale changes to forum structure, expect features to NOT be present when we first come back up that will be added throughout the evening, and possibly into Monday.
Any change requires a little bit of patience and an open mind. Here's what I'm absolutely comfortable saying -- once you've adapted and you're familiar with Xenforo, you're going to wonder how we ever survived on vBulletin. If you don't know how to do something in the new system, just ask, one or more of the people who have been involved with the prep can try to answer questions and point people in the right direction.
XF is made by the original VB developers. It's completely different and modern software, but there's going to be a philosophical and functional familiarity built in for everyone. Please be patient, I expect Sunday to be a very long day for myself, and it may be that I don't get as much done as I want, or it could be that we have problems with the massive data migration that makes that 6 hours substantially longer (oh how I hope that's not the case).
Anyway, we've only a few days left here on vB, which has been our base for a full decade. Pretty crazy. I hope each of you will be and/or become huge fans of the next step forward.
