When you have to completely redesign a successful website with 500K+ views a month, what do you have to think about?
The most important factor is to keep the website successful. In many high-traffic websites, this often times require all SEO factors of a website to remain intact.
There was a requirement to move the jsp-based Findlaw.co.uk website into a WordPress website. I was the sole developer task with porting this website (along with all 3,000+ pages) into the WordPress CMS.
I had to come up with a plan to programmatically copy all the pages and articles from the old website into a format that can be easily imported into WordPress. I also had to retain all URLs and SEO tags are identical to the old website.
I was able to successfully complete this huge project in 2 months and keep the traffic steady.
UPDATE(2017): The FindlawUK division is no longer being maintained.
