How do I migrate a view?
You can do it using this module :
Views D8 Upgrade

Tentative upgrade instructions (these may change):
Before upgrading your site to Drupal 8, update to the latest 7.x-3.x
release of Views on your Drupal 7 site.
Back up your data and place your site in maintenance mode.
Install the 7.x-1.x release of this module.
Navigate to admin/build/views_d8_upgrade and click &quot;Perform upgrade.&quot;
warning: This will copy your Views data and uninstall the
Drupal 7 Views module.
Follow the Drupal core instructions for
upgrading to Drupal 8, including updating this module to its D8
version. This will convert your old Views data (still saved in the
database) to Drupal 8 Views.
