I don't think that's true.
Some services on the internet are already made available through IPv6. Doesn't that mean their migration to IPv6 is done?
There are however some ISPs that seem to be dragging their feet. I recall I tried to deprecate IPv4 access to a personal project of mine and it was no longer reachable when I tried to access it from my home. Lookups from other points of the world could resolve the IP but not my little home network. I felt forced to continue paying the 2€ I paid for a IPv4 address just because of that.
Edit: to make it abundantly clear, I'm looking at you, Vodafone. You suck.
> No, the migration is only done when you're exclusively running IPv6.
I don't think that's an informed, thought-out take. The internet works just fine for all intents and purposes if you have some services reachable through IPv4. There is no obligation to shut down IPv4 in order to work with IPv6.
If you're able to go through your daily work seamlessly hitting services with IPv6, that's a successful migration. It matters nothing if an unrelated service hasn't went through their migration yet.
What I meant was, almost all server operators on the internet have to support either IPv4-only or dual stack. It is still economic suicide to run an IPv6-only server, at least in most areas of the world. As long as you have to run IPv4 software as well and lease an IPv4 address, I would say you are not fully migrated to IPv6.
