Migrating from the old ask.libreoffice site

Hi, where can I read about the change from the old StackExchange-like site, to this Discourse forum? As an online community manager, I’m interested in the reasons behind changing the Q&A platform, and how the migration of existing threads was handled. Thanks!

It doesn’t have keywords friendly to non-technical users (“AskBot” doesn’t tell me anything), so feel free to leave my topic here, closed, for SEO.
