To re-assign cases that meet the 24 hour SLA to the next tier queue, the administrator should use a case escalation rule that defines the criteria for escalating cases, such as age or priority, and the actions to perform when those criteria are met, such as changing owner or sending email alerts. Case escalation rules can help ensure that cases are handled in a timely manner and escalated to appropriate users or queues. Einstein Case Routing, Auto-response rule, and Case assignment rule are not able to re-assign cases based on SLA or age.
