From SharePoint 2007 to SharePoint 2010, I have partially migrated some of our sites. However, since due to the immediateness of the requirement, sites which has issues was left behind the old SharePoint.
Now I am faced migrating a site which has 'People' fields. My problem is whenever I do Export/Import-SPWeb, the 'People' loses value - this is due to the fact that the UserInfo table is incomplete, not all users have logged in to the new site collection.
Is it possible to prepopulate the UserInfo table with what is in the User Profile? Please advise.
