- The forum has its own list, and actually I believe Nokia has little to do with it.
- Garage and Bugs have their own lists
but do you need these services forward?
- About the wiki you could just copy whatever makes sense to keep, and we good with it. Or have a database dump of the content and export it to a new MediaWiki, starting with new users there.
- Users karma would be perhaps lost, but do you mind?
The part that looks more complex is the Autobuilder + Downloads. If a new infra is created based on OBS then perhaps there is a way to transfer all the existing packages and restart the list of owners?
