Doug Lundberg wrote a long Circle review on Convology. Last reviewed May 2026. He has run Convology+ on Circle since early 2020. He also implements Circle for clients and says he has migrated dozens of communities onto it.
This is a consultant page with affiliate links. It is not a first-person dump of one named Mighty Networks community. The useful part is the migration table he is willing to stand behind.
If you are looking at the same route, start with the Mighty Networks → Circle playbook. Circle publishes a concierge migration. Doug’s notes are what he tells clients before that team shows up.
What he says actually moves
Under “Coming From Another Platform,” Mighty Networks is the cleanest source he lists. Community structure maps well. Member data exports cleanly. Courses transfer with some rebuilding. He tells people to plan two to three weeks for a thorough move.
That is the whole how. No CSV column list. No post count. No failed space. I am not adding one.
He also describes one unnamed Mighty Networks client. They had been on Mighty for several years. Admin work felt bloated. A structural change was a project. After the move, setting up access groups took minutes instead of an afternoon. Building a workflow needed no documentation. Members commented, unprompted, that the interface felt cleaner. Those are Doug’s words about a client he does not name.
Circle’s own Mighty comparison says the vendor team exports content and member data, then rebuilds structure in Circle. They claim most migrations finish in two to four weeks. That is Circle marketing. Put it next to Doug’s two to three weeks, not on top of it.
Courses are the part you rebuild
Doug is blunt on courses. Circle’s course features are good, not exceptional. If courses are the product and community is secondary, he would look at a dedicated LMS. On a Mighty Networks move, courses “transfer with some rebuilding.”
Circle’s concierge page is more specific about what their team will not take. Quizzes and assignments do not migrate. They leave a placeholder. Course jobs are billed as about five business days per course, and you need Business annual or Circle Plus. Doug does not say his clients used that concierge path. Treat those limits as Circle’s, not his.
Payments are a separate job. Circle will move Stripe-powered memberships on a concierge track. They say they cannot move transaction history. Doug’s Mighty Networks bullet never mentions billing. If subscriptions live in Mighty’s processor, ask that question before you export members.
What I would copy
Export members first and treat courses as a rebuild. Doug’s split is the useful one. A clean member CSV is not a course library.
Budget two to three weeks if you care about structure, not a weekend import. His unnamed client still had to recreate access groups. That is faster in Circle, in his telling. It is still work.
Keep Mighty Networks up until a known member can see the same spaces and the same course outline in Circle. Doug never describes that check on a named community.
The Mighty Networks → Circle playbook is the object-by-object list. Use Doug’s page for the member-vs-course split, and remember the companies stay unnamed.
