I have till now set a rule that apart from www.example.com if someone types abc/def/anything.example.com the user will get to see the contents of www.example.com This is bcuz of some old sub domains that I couldn't shut off and there were around 2k odd pages that were indexed by google.

Now that those old subdomains can be removed, shall I set a 301 permanent redirection rule for each of those subdomains so that the bots can update accordingly? For instance anything.example.com/test.html will get redirected to www.example.com/test.html
