Question

Is there an alternate way that migrates all parameters implicit? Or any other advantages.

From MSDN:

public void Profile_OnMigrateAnonymous(object sender, ProfileMigrateEventArgs args)
{
  ProfileCommon anonymousProfile = Profile.GetProfile(args.AnonymousID);

  Profile.ZipCode = anonymousProfile.ZipCode;
  Profile.CityAndState = anonymousProfile.CityAndState;
  Profile.StockSymbols = anonymousProfile.StockSymbols;

  ////////
  // Delete the anonymous profile. If the anonymous ID is not 
  // needed in the rest of the site, remove the anonymous cookie.

  ProfileManager.DeleteProfile(args.AnonymousID);
  AnonymousIdentificationModule.ClearAnonymousIdentifier(); 

  // Delete the user row that was created for the anonymous user.
  Membership.DeleteUser(args.AnonymousID, true);

}

Or is this the best/only way ?

Answer 1

This is the way to go. But I would suggest a generalization. Instead of hardcoding each property you could loop through the ProfileBase.Properties collection. Something along these lines:

var anonymousProfile = Profile.GetProfile(args.AnonymousID);
foreach(var property in anonymousProfile.PropertyValues)
{
    Profile.SetPropertyValue(property.Name, property.PropertyValue);
}

Since property groups are represented as part of the property names (e.g. “Settings.Theme” represents the Theme property within the Settings group) the above code should also work with property groups.
