Salesforce reserves just five minutes of scheduled maintenance time to roll out new
major versions of our service. These upgrades to the next release occur three times per
year.
Required Editions
| Available in: Salesforce Classic |
| Available in: All Editions |
Although your organization should expect to experience a disruption of up to five
minutes, the interruption is typically one minute or less. Users receive an error
message letting them know that the service is unavailable during the upgrade, and are
prompted to log in again when the upgrade is complete.
