A computer-implemented method for propagating changes to a live website includes logically moving a second immutable delta partition located in a staging database of a staging environment to a production environment. The second immutable delta partition is a replica of a first immutable delta partition located in the staging database of the staging environment. The computer-implemented method further includes logically moving a second delta index located in the staging database to the production environment based on altering the second delta index for the staging database to reference: (i) unique network addresses corresponding to data partitions located in a production database of the production environment and (ii) a unique network address of the second immutable delta partition located in the staging database.
