Define Drupal Site Requirements

Determine how your users will interact with the legacy data on the new site

Is there any legacy data that can be leveraged to create new content? Example: using an address record to populate a Google Map

Will content need to be re-categorized in the new site?

Sizing Up Legacy Content

Where does your content “live” and what format is it in?

Determine which parts of legacy content will be used on the new site and what new meta data will possibly need to be added during the export

Prepare Content Export

Generate CSV file containing legacy content data (most Drupal contributed modules have CSV support)

Make sure steps to generate CSV file are well-documented, especially if making complex data transformations in the export logic

Drupal Content Basics

A “node” in Drupal is the general term for describing a unit of content. A node can be a story, blog post or page for example.

A “node” in Drupal is the general term for describing a unit of content. A node can be a story, blog post or page for example.
A “content type” is a collection of fields that make up a node. Nodes can have one or more data fields and the content type serves as a container for those fields.

Title field

How is Legacy Content Stored in Drupal?

Imported data is matched to a specific content type by way of a Drupal module or custom PHP / MySQL scripts

Legacy content fields map to various content types’ fields such as text, numbers, checkboxes / radio button groups, categories, images, etc.

Legacy content fields map to various content types’ fields such as text, numbers, checkboxes / radio button groups, categories, images, etc.
Each row of the CSV export file becomes a node in Drupal’s database

Methods for Importing Content to Drupal

Drupal contributed modules such as Node Import, Migrate and Transformations. See http://groups.drupal.org/node/21338 for comparison of various Drupal data export/import modules

Custom PHP scripts (it’s possible to bootstrap just the database layer of Drupal to cut down on the code required) or custom Drupal modules
