Migrating SharePoint 2010 workflow from SharePoint 2013 to SharePoint 2016

Question

Currently SharePoint 2010 style workflows are running on SharePoint 2013 farm on Domain1. I want to migrate site collection to SharePoint 2016 on Domain2 using database attach method. My questions are:

1. Will workflows continue from where they were left on old farm? Or will I need to restart all workflows?
2. What will happen to users in workflow as I am migrating to a different domain? Let's say a workflow is currently pending at user@domain1 and the same user exists on domain2 so will workflow work seamlessly?

Hi @Frank Martin ，
Based on my research,

1. You need to install and configure workflow manager 1.0 in SharePoint 2016 environment.
2. You can take a backup of workflow manager DB and restore it in SharePoint 2016 environment.
