Rewrite old post images to https

It’s very primitive method but works in any case;

  • Make a dump from MySQL
  • Open it with text editor or maybe another tool you liked (If your dump is so big, you’ll need a strong computer.)
  • Find all http://example.com, replace with https://example.com and save.
  • Rename/move the old database for backup, import the edited database.
  • Leave the cave and go hunting.
