Redirecting regional pages - update sitemap?

[marley23]

Hi,

I previously had 7 different versions of a website for different regions (/us, /can, /nz etc.) but the pages were all identical to the equivalent pages on the .com site and therefore having issues with ranking. I've redirected all of the regional pages to our .com site now. Our sitemap still contains all of the regional variations, at what point should I remove them from the sitemap? Do they need to stay in there so google can still crawl them to the redirected pages?

Thanks
