We have done 6 upgrade projects and had failed on 1 project (3 times)<br><br>3 from 4.7 to 5.x ( Very large sites)<br>3 rewritten from 4.7 to 6.x (small/medium sites)<br>We tried to upgrade 1 project from 4.7 to 5.x. We did this thrice but haven't been successful. We are now rebuilding the site entirely in Drupal 6 with lot more enhancements/new features. <br>
<br>Whenever we do a major upgrade, one of the biggest challenges we have is to ensure that URL structure is retained so that sites don't lose their traffic after upgrade. There always has been a dual challenge to get the client the benefits of new modules/features and a better URL structure, breadcrumb, etc and at the same time preserving the old ones.<br>
<br>We get at least 3 to 4 leads every month from clients looking to upgrade their Drupal sites. Most of them think its a 3 day job (maybe there is a wrong marketing message out there where people think its soooo easy to upgrade Drupal) and we just ignore such requests.<br>
<br>There is so much involved in upgrade project. We at least do 2 dry runs before going live!<br><br>Roshan<br>--<br>Gloscon Solutions Inc - <a href="http://www.gloscon.com/portfolio">http://www.gloscon.com/portfolio</a><br>
