Push Package Upgrades to Subscribers
A package subscriber doesn’t need to do anything to receive the push upgrade. The only indication a subscriber receives after a successful push upgrade is that the package’s Version Number on the Package Detail page has a higher value. The developer initiating the push resolves upgrades that fail.
Use the Push Upgrade Exclusion List to exclude specific subscriber orgs from a push upgrade. You can specify up to 500 comma-separated org IDs.
Push upgrades minimize the potential risks and support costs of having multiple subscribers running different versions of your app. You can also automate many post-upgrade configuration steps, further simplifying the upgrade process for your customers.
The push upgrade feature is only available to first- and second-generation managed packages that have passed the AppExchange security review. To enable push upgrades for your managed package, log a support case in the Salesforce Partner Community. For details on the security review process, see Pass the AppExchange Security Review in the ISVforce Guide.
