I have completed a domain add-on for my blog and routed it to my old directory (.com.au/blog)
My blog used to be [xxx.com.au/blog] and now I it is [xxx.com].
I have updated my .htaccess and Wordpress URL and Site name. All is now directed to the new Domain URL.
The name is the same. The only essential change is from .com.au to simply .com
In Google and Bing should a new domain and upload a new sitemap (.com) or do I just leave the sitemap, domain url and associated analytics as the old domain (.com.au/blog)
