Indexes are independant.

If you meant index keys like parent primary key and child foreign key they are only automatically updated if set via referential integrity. Otherwise you should update yourself.

On the other hand such keys seldomly need an update. When you need an update on those keys you should ask yourself "did I do this right from the start ".
