Modifying Class Key which has around 1 Million instances

Hi All,

We have a class who key is defined as say Column A.

There are around 1 million instances of this class. Now we have to modify the key of this class and include another column, say column B, as key.

I know that we have to delete the instances, then update the class rule to add the new column as key. But the problem is updating all the 1 million records with an one time activity to open and re-save will take a lot of time.

We want to know if there is any alternate way of doing this.
