Hi Ernest,
actually, before using ASPs migration procedure, I tried migrating the database using Migrate DB Pro, which resulted in “WordPress database error: [Unknown collation: ‘utf8mb4_unicode_520_ci’].
So I guess those _mig_ tables were created by ASP.
What I don’t understand is why ASP told me that it “successfully imported 2 search instances”, but then did not display them anywhere (nor did I see any ajaxsearchpro tables anywhere in MySQL).
Anyway, it seems to work now 🙂
Thanks, Phil
