I built a community in CS2008.5 for a client that makes heavy use of group pages for content. When I upgraded the client's database for Telligent Community 5, I discovered that all of the group page content had been destroyed. (I didn't upgrade the production DB of course.) This seems like a pretty serious defect in the upgrade process, since it destroys content.
I understand from Ken Robertson that Telligent's vision is to use Wikis to replace the group pages feature, which is fine. In that case, the database upgrade scripts should create Wiki sections in groups to preserve page content.
Thanks for dealing with this.
