SharePoint migration 2010 to 2013, User Profile Mismatch/issue

Question

I have migrated SharePoint 2010 to 2013 and then 2013 to 2016 with Database restore method.

I am facing issue, We have unique permission in every list item. While checking I found that migrated list item user have ABCDomain\nm002u account name and when I add any user from SharePoint 2016 to permission page then it shows i:0#.w|ABCDomain\nm002u account name.

So, all views filtered with [Me] is not working and user cannot able to see any list item due to user profile mismatch.

How to resolve this issue.

You will need to migrate your users from Classic to Claims. The easiest way to do this is with the Convert-SPWebApplication command in Powershell, or you can use the Move-SPUser command.
