Migrate ASP.NET Membership Authentication to ASP.NET Identity 2.1 (MVC5)

Hello Guys,

We are planning to migrate ASP.NET membership to ASP.NET Identity could you provide any best solution as i have tried couple of example as below but none of them worked, I am using MVC 5

Example 

http://travis.io/blog/2015/03/24/migrate-from-aspnet-membership-to-aspnet-identity.html

http://kosmisch.net/Blog/DotNetEssential/Archive/2015/2/1/aspnet-membership-default-password-hash-algorithms-in-net-4x-and-previous-versions.html

http://www.asp.net/identity/overview/migrations/migrating-an-existing-website-from-sql-membership-to-aspnet-identity

Always failed below line

String.Equals(EncryptPassword(providedPassword, passwordformat, salt), passwordHash, StringComparison.CurrentCultureIgnoreCase)

Could anyone provide complete working example please with MVC5

Thanks in Advance
