Hi @davidva! Welcome the the new AskFedora!
Yes, to combat spam, generate useful metrics, and make it easier for users to turn into contributors (with FAS creation as the first step), we’ve decided to limit logging in to FAS only.
Unfortunately, there is no clear way to migrate information from askbot to Discourse—we’re not hosting this instance either, so we don’t have access to the low-level database etc. anyway. So, we’ve worked on moving common questions to the quick-docs, but that’s all. We’ve all had to drop the karma/badges and start over.
Discourse, however, has (in my opinion), an even better trust system, so I do expect new users will quickly be able to go through the gears and earn their badges and permisisons too.
More on that here: https://blog.discourse.org/2018/06/understanding-discourse-trust-levels/
