Background

When we move the Drupal 7 workflow information from the old site to the new site we need to keep the information intact and accurate. To do this, we need a plan which will account for:

Consideration

Challenges

Ideas

User Accounts Should Be The Same

  • Drupal 8 User Account Migration

  • If we don’t import the User Accounts from the old website to the new website, then the users will be logging in with different accounts. Is it possible to import users from one instance to another?

  • How does the database backend for the Workflow system associate information with User Accounts? If we import user accounts, will this change an internal unique identifier such that the Workflow data no longer lines up correctly with User Accounts?

Date / Times Should Be The Same

  • We can’t hand enter this data, as it will have different dates/times.

  • Is there a migration tool for this?

  • Can we do this with direct SQL?

Workflow Action Notes Should Be The Same

  • We should ensure these get brought across to the new website.

  • If we can figure out the Date / Times, we should be able to figure out this, right?

If we import the data into the new site, but continue to use the old site for a bit longer, we should also have a plan to keep the audit/decision information synced between the two.

  • How can we sync these?

If direct drupal Migration is not an option

  • This has proven to be the case, as the Workflow module in D8 is in alpha. The alpha release has all functionality of the original module, however it does not have the migration functionality implemented

  • We need to determine possible ways of migrating:

    • The workflows

    • And the data (all the things listed above)

Comparison of Migration Options

Option 1: Find Script on Internet

Option 2: Write a script ourselves using Drupal Migration Code

Option 3: Write a script ourselves using direct database calls

Option 4: Hand migrate

Description

In this option, we have tried a related option that is available on the internet and takes the idea if someone already did migration in order to investigate.

Workflow Rules

Pros (plus)

Cons (minus)

Data

Drupal site is having 2 workflows i.e “API Publish” and “Application Approval Request” which will have their certain state respectively.

Pros (plus)

Cons (minus)

Notes

On the basis of research on the internet, there is no direct way available to migrate workflow and rules directly from Drupal 7 to Drupal 8.
Here is the list of the POC:-
1: I have tried migration through the Drush commands. These steps are given in the doc Migration Process from Drupal 7 to 8

Result: Failed, I have tried to migrate workflow and rules data through the brush but the process is not supported to migrate the data from D7 to D8.

Useful Link: https://www.drupal.org/docs/upgrading-drupal/upgrade-using-drush

2: Tried to import workflow state by adding code and followed steps mentioned here in this link https://www.drupal.org/docs/upgrading-drupal/upgrade-using-drush But there is not success found with that.

Result: Failed, As node was not imported to the D8.
