There are a lot of good articles out there that can help you with this. This is more of specific examples on how to do it between 2 localhosts.
Some references:
Preparing for an Upgrade (READ FIRST)
Simple, but will write this up later. In the interim: https://drupalize.me/tutorial/drupal-drupal-migration-ui?p=2578 check that out
You will need a few extra modules to get started with this route: Migrate Tools, Migrate Upgrade & Migrate Plus
Double check if you need any special modules for your content as mentioned in the Preparing for an Upgrade link above.
Kalabox
Currently can't enable Migrate Upgrade module - see issue: https://github.com/kalabox/kalabox/issues/1789
Drupal VM
In the D8 site run this
drush migrate-upgrade --legacy-db-url=mysql://drupal:drupal@localhost/D7SITE_drupalvm --legacy-root=http://D7SITE.dvm --configure-only drush migrate-status |
You can migrate all of the items with:
drush migrate-import --all |
OR you can be more granular and migrate only certain items:
drush migrate-import {migration name} i.e. drush migrate-import upgrade_d7_menu drush migrate-import upgrade_d7_node_news |
Use this option if you need to be more granular in your migration. You can also use this to change the names of items, etc. There are a lot of great resources out there on how to do super duper custom configs. This is just a simple example.
Drupal VM
Do the following in your terminal on your D8 site (change our YOUR-MODULE as need be):
vagrant@dvm:/var/www/YOUR-SITE/web$ drupal gm // Welcome to the Drupal module generator Enter the new module name: > YOUR-MODULE Migrate Enter the module machine name [YOUR-MODULE_migrate]: > Enter the module Path [/modules/custom]: > Enter module description [My Awesome Module]: > The Migrate Template for YOUR-MODULE Enter package name [Custom]: > YOUR-MODULE Enter Drupal Core version [8.x]: > Do you want to generate a .module file (yes/no) [yes]: > no Define module as feature (yes/no) [no]: > Do you want to add a composer.json file to your module (yes/no) [yes]: > Would you like to add module dependencies (yes/no) [no]: > yes Module dependencies separated by commas (i.e. context, panels): > migrate_drupal, migrate_plus, migrate_tools, migrate_upgrade Do you want to generate a unit test class (yes/no) [yes]: > no Do you want to generate a themeable template (yes/no) [yes]: > no Do you confirm generation? (yes/no) [yes]: > yes Generated or updated files 1 - /var/www/YOUR-SITE/web/modules/custom/YOUR-MODULE_migrate/YOUR-MODULE_migrate.info.yml 2 - /var/www/YOUR-SITE/web/modules/custom/YOUR-MODULE_migrate/composer.json |
Run this in the D8 site:
drush migrate-upgrade --legacy-db-url=mysql://drupal:drupal@localhost/D7SITE_drupalvm --legacy-root=http://D7SITE.dvm --configure-only drush config-export --destination=/tmp/migrate |
Run this:
cp /tmp/migrate/migrate_plus.migration.* /path/to/YOUR-MODULE_migrate/config/install |
