Thanks much Andrea, I'm so very new to SEO and all the errors freaking me out!

Yes the migration changed the URL structure.  I thought I went through them very carefully to make sure each URL matched (not sure why not all of the URL successfully submitted with matched URLs).

I also upload all the previous redirects via Yahoo onto the new platform.

I updated the new sitemap to the search engines (Google, Yahoo)

For example, the below links showing as errors and can't figure as too why.  I updated the sitemap:

But also strange that when migrated and w/ all these errors the website is getting double amount of traffic??

Hello -

I'm working on a website selling fashion accessories.  The site just went through a site migration from Yahoo! to Big Commerce.  Now we have a high level of warnings and errors from the crawl.  Few are mentioning sites I never seen before on the Yahoo! platform. I also notice that the pages crawled has doubled.  How can I fix or did I do something wrong with migration?

I was running the website with minimal errors and now overwhelmed with errors all the error updates.  If I can get some assistance on what could be wrong, I would greatly appreciate.

Thanks.
