Trying to change the profile of logged in user through apex

Question

My requirement is when a user logged into customer portal using credentials-profile has to be changed when a action is called on button-click. At the time of login -profile is say 'abc'. I have called a future method onclick of a button to change the profile to say 'xyz'. I am able to change the useremail but not the profileID,it is showing the following error: FIELD_INTEGRITY_EXCEPTION, Cannot change profile for current user: Profile ID

My future method is as follows:

@future public static void updateuserAFL(id userId,id profileid){ User tempUser = [select id,name,Email,Username,Profileid from user where id=:userId ]; tempUser.ProfileId=profileid; tempUser.Email='test@mphasis.com'; update tempUser; }

Can anyone please help me how to change the profie of the logged in user..

Please have a look once on below link to update user profile using apex code.

update user profile through apex

Here we are doing a HttpCallout, which in result update user profile as admin mode.

public void callPublicSite(){

     String remoteURL = 'https://testing.force.com/ProfileUpdate?userId=' userId+'&profileId='+profileIdToUpdate;

     HttpRequest httpRequest = new HttpRequest();
     httpRequest.setMethod('GET');
     httpRequest.setEndpoint(remoteURL);
     HttpResponse httpResponse = new Http().send(httpRequest);

} 

//page name: ProfileUpdate

public void doProfileUpdate()
{     
   try
   {
      String userId = ApexPages.currentPage().getParameters().get('userId');
      String profileId = ApexPages.currentPage().getParameters().get('profileId');
      update new User(Id=userId,ProfileId = profileId);
   }
   Catch(Exception e)
   {
     System.debug('::::user profile not update'+e);
   }
}
