Migrate Drupal Webform 6 or 7 in to Webforms in Drupal 8

Webform 8.x-5.x is a completely new code base, that takes a different, but familiar approach to solving the challenges of building rich, flexible, and maintainable client facing forms for a Drupal website. Webform 8-x-5.x includes many new features and leverages improvements in Drupal 8, including OO design patterns, extendable plugins, and automated tests.

The primary use case for this module is to:

• Build a new webform or duplicate an existing template
• Publish the webform as a page, node, or block
• Collect submissions
• Send confirmations and notifications
• Review submissions online
• Download submissions as a CSV

So how do we get all the Drupal 6 or 7 webforms in to Drupal 8 is what we are going to details here. I did a little bit of research but I couldn't find any solution so I came up with this module Webform migrate to help with those kind of data migrations.

Webforms in D8 are configuration entities and submissions are content entities, Webforms OOP architecture clearly described each component in a very details oriented way so the migration set up was very easy.

So to get started please download the module here from GitHub and install it.

Then use the configuration import and use the migration templates available in the module and import them. If you set up the Migrate Plus module at the same time you install the Webform migrate module then during the migration it will look for those templates too. Either way get the configurations imported.

Once the configs are imported then you can run the migration to import Webform data, simple as that.

Sample configurations are below for Drupal 7 to Drupal 8 migration.
