Copy/Move items from one list to another list in sharepoint

Scenario:

List AA fields: Name, Title, User Name, Religion, Qualification.

List BB fields: Name, Title, User Name, Qualification, Designation, Salary and Description

Common field names: Name, Title, user name, Qualification

Now, I want to copy the common field values from List AA to List BB.

Approach:

//Read the list item values by ID and add the common field values as new item into the another list

SPListItem spLstItemsAA = listNameAA.GetItemById(ItemID); //ItemID of List AA

SPListItem spLstItemBB = list.Items.Add();

foreach (SPListItem spLstItemAA in spLstItemsAA.ListItems)

{

       for (int i = 0; i < spLstItemAA.Fields.Count; i++)

       {

          if ((!spLstItemBB.Fields[i].Hidden) && (!spLstItemBB.Fields[i].ReadOnlyField) &&    

                                  !(customfields.Contains(item.Fields[i].Title)))

           {

               spLstItemBB [item.Fields[i].Title] = spLstItemAA [item.Fields[i].Title];

             }

        }

 }
 spLstItemBB ["Salary"] = "50k";
spLstItemBB ["Description"] = "sharepointquicksolutions.blogspot.in ";
spLstItemBB.Update();

Condition#1: !spLstItemBB.Fields[i].ReadOnlyField

Condition#2: !spLstItemBB.Fields[i].Hidden

The above 2 conditions are used for to skip the read only and hidden fields.

Note: By default, every sharepoint list and library will have the below fields.
