For the second part of my migration blog, I want to touch on the importance of maintaining URLs from your old site and demonstrate some examples of how to capture them in Drupal. Search engine traffic and other referrals are invaluable when it comes to the success of a site. I've managed sites that have received upwards of 100,000 referrals a day from Google alone. This is not even to mention all of the external links and bookmarks to your pages. If you are thinking about migrating to Drupal and have not considered the importance of maintaining old URLs, you definitely should. The impact of losing that amount of traffic could be catastrophic, but luckily the solution is reasonably simple.
