I made an error when bulk 301 redirecting from an old domain to new domain with same url structure. Google bot followed the 301 redirect for each page on the old site to my new site, which gave a 404 error. I tested it browser in worked for a user but somehow did not work for the google bot and I detected it too late.
I fixed the error now and the pages could be (hopefully) accessed by google bot at their new urls.
Question: will google recrawl 301 redirects which led to 404?
