Changed cms - google indexes old and new pages

[Tit]

Hello again,

after posting below problem I have received this answer and changed sitemap name

Still I receive many duplicate titles and metas as google still compares old urls to new ones and sees duplicate title and description....

• we have redirectged all pages properly

• we have change sitemap name and new sitemap is listed in webmastertools

- old sitemap includes ONLY new sitemap files....

When you deleted the old sitemap and created a new one, did you use the same sitemap xml filename? They will still try to crawl old URLs that were in your previous sitemap (even if they aren't listed in the new one) until they receive a 404 response from the original sitemap.

If anone can give me an idea why after 3 month google still lists the old urls I'd be more than happy

thanks a lot

Hello,

We have changed cms for our multiple language website and redirected all odl URl's properly to new cms which is working just fine.
Right after the first crawl almost 4 weeks ago we saw in google webmaster tool and SEO MOZ that google indexes for almost every singlepage the old URL as well and the new one and sends us for this duplicate metatags. 
We deleted the old sitemap and uploaded the new and thought that google then will not index the old URL's anymore.

But we still see a huge amount of duplicate metatags.

Does anyone know what else we can do, so google doe snot index the old url's anymore but only the new ones?

Thanks so much

Michelle

Hi Michelle,

If you have redirected from old URLs to the new ones properly, uploaded the new sitemap, you shouldn't worry about that.

Google webmaster tools is a little-bit slow on gathering and analyzing data (we have seen similar situations in the past).

The only concern is that you properly redirect the old URLs to the new ones.

Good luck!
