Modifying a Cluster
After you have created a cluster, you can modify some of its configuration options. For example, you can
associate a different parameter group or security groups.You can also change the cluster maintenance
window, the master user credentials, and the automated snapshot retention period. All of these changes
take effect only after the cluster is restarted.
If you decrease the automated snapshot retention period, existing automated snapshots that fall outside
of the new retention period are deleted. For information about working with snapshots, see Amazon
Redshift Snapshots (p. 52).
