Hi,

I was wondering if you have any tipps on the following situation.

I'm going to move a large website to a new Content Management System, here are some details on the site:

• online news magazine with roughly 3,000 articles
• domain age: 10 years
• online in the current form since May 2010
• indexed pages: ~10.000
• percent of search engine traffic: under 10%

Unfortunately a custom-tailored CMS was used for the site. The performance, reliability and SEO capabilites have been really bad, so we are moving to a new and proven open source CMS.

All the articles will be kept as they are, but the URL structure as well as the structure of the HTML templates will be changed.

What I wanted to do now is to actually create 301 redirects for all articles from the old to the new schema, i.e:

• Old: www.example.com/en/html/news/detail/title-of-the-article/
• New: www.example.com/category/title-of-article.html

Is this a proven way to do something like this? If not, can you recommend a way that has worked for you?

Thanks :)
