Subject Re: rename index

I haven't tried this, but it should work in theory...

Keep the wrongly named index for now.  Create the rightly named index,
then bring down the node and swap file names for the indexes.  After
that, you can safely drop the wrongly named index.  Unfortunately,
you need to do this for each node.

Gary.
