Ecommerce used to be the preferred ecommerce solution for Drupal before Ubercart came into the picture. We recently worked on upgrading a Drupal 5 site with Ecommerce to Drupal 7 with Ubercart. The challenge with this upgrade was that the source data existed only in the D5 database and the corresponding code to programmatically access the ecommerce data was in D5 as well while the destination tables existed only in the D7 database with the corresponding code existing only in the D7 database. The solution we went with was to go for a full SQL query based migration to copy over the Ecommerce data from its tables to the Ubercart tables.

The full migration process was created as a re-executable sql script because we had to iteratively fix issues in the migration. The following set of sql queries were used in the migration. We hope this helps someone trying to Migrate Drupal Ecommerce module to Ubercart. Contact Us if you need help with migrating from Ecommerce to Ubercart or for that matter migrating from any system to Drupal + Ubercart.

Upgrading a Drupal site refers to moving it’s database and files from one major version of Drupal to a later one, to take advantage of the newer features and bug fixes that might not be available for the older version. Upgrading a Drupal site is a pretty effective way to make sure that your Drupal site is currently up to date with all the latest security updates and bug fixes. Old versions of Drupal will naturally be unsupported with the arrival of the new releases. The Drupal community has currently stopped supporting the older versions of Drupal like version 4 and 5 and has moved to Drupal 7. However Drupal 6 is more widely supported. Have a look at the steps required to upgrade your Drupal site from an older version to      Drupal 6.      Web Development Drupal Drupal 6 Drupal 4 Drupal 5 Drupal Upgrade Leave a reply Your email address will not be published.

When migrating from Drupal 5, the normal path would be to migrate everything (core/modules/themes) to the latest Drupal 5 versions, and then to the latest Drupal 6 versions, and then over to the Drupal 7 versions. How fortunate would have been the developers assigned the job if everything was as simple as that!
