Can I globally set any Acknowlegement to expire (auto-unack) after a period of time?

[Ben Gardella]

When on-call assignments change, all previous "acked" alerts remain acked and silent indefinitely.  I would like any acked alerts to revert to "unacked" after a period of time.  Like a day or two.  How do I do that?

Have you tried adding a notification policy to 'auto restart' after X time?

Hi @Ben Gardella ,

Like @[deleted] mentioned, we see most customers adding a Notification Policy that is configured to restart notifications after X-time following when the alert was created: https://docs.opsgenie.com/docs/team-policies#notification-policy 

These can be configured under a team's Policies tab and would look something like this:

Alternatively, if your alerts notify users through an escalation policy, you could repeat that escalation's rules and revert the alert back to an un-ack'd state:

Either option works! Simply a personal preference between one or the other. Let us know if you have any additional questions or issues.

Thanks. I'll try option one and see how it goes.

These two alternatives seem to have different side-effects if you have multiple integrations on the same alert. 
When using the first option(with notification policy on teams), whole alert life-cycle restarts and re-triggers any other integrations you may have. 
The second option only loops through the escalation rules so any other integrations are not notified.
