Strangler fig pattern: has anyone actually completed a full migration?

We're two years into a massive strangler fig migration, trying to break down a legacy monolith into microservices. We're probably about 60% done for our critical paths, but the momentum has really slowed down. It feels like we're perpetually in migration mode, and the remaining 40% involves the trickiest, most intertwined parts of the system. My question is, has anyone actually *completed* a full strangler fig migration from a truly large, complex monolith? Or does it more often turn into a perpetual hybrid state where some core pieces never quite get fully extracted? We're particularly struggling with shared database tables that are still accessed by both the old monolith and the new services, leading to tricky data consistency issues. Any insights on how to regain momentum, or practical advice for handling these particularly stubborn parts of a legacy system that resist being 'strangled'? Is full migration a realistic goal, or should we adjust our expectations?
