Preparing for Drupal 8 migration

Preparing servers

Since Drupal 7 to Drupal 8 is not done on single instance, We have to install fresh Drupal 8 and migrate content and themes to new Drupal 8 instance.

Upgrading Drupal 7 to latest drupal 7 version

This is the best approach while migrating older Drupal 7 version to Drupal 8. Because for running migrate modules smoothly we need to ensure core files and database tables are latest.

Prepare catalog of Current Drupal 7 Website

Before migration starts  we have to list out components in current websites, this will be helpful in moving forward. Keep an excel sheet or any comfortable document where list out all content types , modules , views,taxonomy , custom blocks etc.

there is no migration path for view configurations. so list out all views which currently using , this need to be manually created during migration.

Install fresh Drupal 8  from drupal.org

download and install latest Drupal 8 version from drupal.org.

List of contributed modules installed

Prepare list  of contributed module list in existing website(Drupal 7). We have to check for each contributed modules Drupal 8 version is available or not. Most of the major modules have corresponding production ready Drupal 8 version available. But for some modules it will be in alpha or beta stage. Some contributed modules are now part of Drupal core. Also modules may not be available in Drupal 8. For modules are not available in Drupal 8 we have to analyse for which functionality it is using  and install alternate module in Drupal 8  that will do same functionality. If it is not available create custom module which will do same functionality. But most of the modules are available in Drupal 8.

Below is the some major modules which is already available in Drupal Core.

Views , CKeditor etc

install all available modules in new Drupal 8 instance. Then only corresponding module contents migrated during  migration process.
