For me, notably absent from the release changelog and accompanying YouTube video they were excited to trumpet in the blog back in July, and the claim (still) this took 11 days. It's August 20th.
I guess this is much reduced by now, and the effort required on that front should not be rejected from being part of the migration.
But if they went down in cpu usage and memory usage, removed a memory leak, and are MORE compliant with nodejs... it sounds like a MASSIVE success?
