migrate drupal 6 to drupal 7

Hi Deepak,

It depends on your requirements for the upgrade - so more information may be required to fulfill your request.

1. Migrating content type data should be fairly straight forward between major versions. Were there any customizations done / custom content types made on the Drupal 6 site (e.g. using Content Construction Kit module (CCK))? If so you would just need to install the latest version of the CCK module on the Drupal 7 site, and any other custom modules that were required (e.g. Node Reference which is a separate module in Drupal 7).

2. Users should migrate without issue. It sounds like you want to change role information during the migration? Do you have more specifics about what you're trying to do? User and Roles are part of core so upgrades of those shouldn't be an issue; however, if you're trying to change information based on something that is identifiable you could modify during the upgrade via Drush, SQL Query, or Views Bulk Operations module once the upgrade has been completed.

I hope this helps.

There is no migration system in Drupal 7 core, this support request should be in the Migrate project.

Please read the Migrate documentation which already contains examples: https://www.drupal.org/node/415260

I've read somewhere in your project description that D8 support is coming soon?

The Migrate project has been moved into Drupal 8 core. The documentation can be found here.
