Migration from Woltlab 6 to Discourse

I volunteer to run the forum https://intensivpflege-familie.de; since the forum is currently more static but is a knowledge base for families with seriously ill children, I would like to move to Discourse. The background is the license costs for Woltlab, which are too high for me for the current use in a volunteer capacity, and the hope of being able to retain people again with a modern design.

The forum runs on Woltlab 6.1x

Therefore, I am looking for a way or help for the migration. Unfortunately, I haven’t found anything suitable for Woltlab 6.

Only the minimum that should be migrated is needed:

Users (Name, E-Mail, CreatedAt, possibly Avatar)

Groups (only as Discourse Groups, without permission mapping)

Structure: Categories + Subcategories (roughly corresponds to Forums/Subforums)

Topics/Threads → Discourse Topics

Posts → Discourse Posts

Optional: Uploads/Media (Attachments/Images in Posts)

Everything else (permissions, moderation roles, badges, trust levels, category rights, SSO/OAuth, PMs) I would set up afterwards. Users can also be migrated as “Staged Users,” as I learned that users will be “matched” upon registration. Or if users are migrated, it can be without a password; users can create a new one themselves.

All other things realized with plugins would be discontinued.

It is a small forum with 211 members, a good portion of whom are inactive, and just over 14,100 posts.

I have no orientation for a budget for this; depending on the costs, I have to decide whether I should rather leave the forum readable (which is bad because of security updates) and if I receive financial help as a donation.

Best regards

There is no current importer for Woltlab, hence I am moving this to Marketplace in the hope that someone will make you a good offer to help.
