How do I change my workspace's retention period?

1) Sign in as an owner or admin and go to Configurations, then Plans. 2) Click the "Retention" button at the top of the page; it shows your current period in months. 3) Enter the number of months you want. A shorter period than the included 36 months costs nothing. For a longer period, Deskhero shows the rate, how many tickets currently fall in the extended period and the estimated monthly cost, and asks you to approve the recurring charge. 4) Click "Save retention preference". The change is recorded in the billing history.
