Hi  
I already have an index with the size 89GB. Forgot to add all the rollups in the initial stages. How do i proceed with the rollups. Now want to create an index for each date.Is it possible to do rollups for an existing index and moving the data which is being created will have index with date as suffix.

Can anyone help, please.
