I'm currently in the process of migrating from SharePoint 2010 which uses classic authentication to SharePoint 2013. The steps I have taken are:
- Created a new classic web application on SP2013
- Mounted the SP2010 DB via Powershell which converts the DB
- Converted the web application to use claims based authentication
- Migrated the users
The issue I am having is that a new user row is created in the UserInfo table. This is getting a new ID which is adding a new user profile in SP. When I create a document, it is created under the new user id, and not the old one. So when I click on the user name(same name) under the last modified user, the documents created in 2010 point at a different user to the ones created in 2013.
Is this normal behaviour? If not what am I doing wrong?
