Please read the note below from our OneSite Project Manager:

Hi Ken,

The plan is to migrate the forums Tuesday morning. It shouldn't take longer than an hour and a half. There will not be redirect in place at the time but we will be able to import any new posts made during that time. It would be best to alert users that they should not post during that time. The plan is to begin migration at 9:00 a.m. (CDST) on Tuesday. That will be 10:00 a.m. your time (EDST).

It will take approximately 45 minutes to migrate and then there will be approximately 20 minutes more of changes and cleanup before the new forums will be ready to go.

Have a great weekend.

Kara
