Migration from ASP.NET Membership to SimpleMembership
View migration.sql
--This script attempts to migrate the users
--from the old ASP.Net Membership tables
--into the new SimpleMemberShip tables
--The SimpleMembsership uses more secure password hashing, as such the old password hashes won't
--work with the SimpleMembership tables.
--As far as I can tell you have two options
--1) Get your users to reset their passwords
--2) Update your web.config to force SimpleMembership to use the old SHA1 format. See more details
