Upgrading a Tripal 3 site

The upgrade path is still under development. More information will be added here as it becomes available.

What we know so far:

• Upgrading from Drupal 7 to 8+ requires a migration.

  • This means you will create a local copy of your current Drupal 7 site, a new Drupal 8+ site and then use the Drupal Migration module to transfer your data from the Drupal 7 site to the new Drupal 8 one.

  • This process ensures unused or old configuration from previous upgrades is not transferred to your new site.

  • More information can be found here: Upgrading from Drupal 6 or 7 to Drupal 8 (and newer)

  • Drupal has provided the following documentation to prepare for a migration: How to prepare your Drupal 7 or 8 site for Drupal 9

• Upgrading from Tripal 3 to 4 will also use the Drupal migration functionality.

• Only Chado 1.3 will be supported in Tripal 4 so you need to upgrade Chado first.

• No re-loading or changing of Chado data will be required by the migration.
