Earlier today i upgraded one of my low-traffic/simple sites from D5 to D6. It went very smooth and I was done in less than an hour. But now i am planning on upgrading my larger, high-traffic, more complex (more modules & customization) site to D6 so i am wondering if anyone has any horror stories (or success stories) to share before i jump in.
I don't have any but I read a good write up on a Drupal upgrade the other week. http://drupal.org/node/545034
I upgraded my one Drupal site from version 5 to version 6 without any problem. Make sure you check modules you are using is available for version 6 and use the right version modules. You can also try to upgrade first on local system by installing wampserver.
well the upgrade went "ok" .. I had some major glitches that took a few hours to work out, and minor glitches/annoyances that i've been working on for a week.. but overall, the upgrade went pretty well.
