Before You Install an AppExchange Package
Before you install a managed package from AppExchange, review any limits or requirements, and consider trying a Test Drive first.
Take a Test Drive
A test drive is a fully functional Developer Edition Salesforce environment that contains the managed package. Go to AppExchange, find a solution, and click Test Drive to try out the solution before you install it.
Verify Requirements
Every package has its own requirements. To verify that a package is compatible with your Salesforce org, review any requirements listed in the solution’s listing.
Understand Edition and Org Limits
Consider how installing a managed package impacts edition and org limits in each of these scenarios.
| Scenario | Impact on Edition or Org Limit |
|---|---|
| Custom objects, custom fields, tabs, and apps from a managed package installed from AppExchange. | These components don’t count against your edition allocation, but they do count against the total limit for your Salesforce org. |
| Custom objects, custom fields, tabs, and apps from a managed or unmanaged package not publicly listed on AppExchange. | Custom objects, custom fields, tabs, and apps count against the allocation for your Salesforce edition. |
| Components from an expired or suspended managed package. | Custom fields in an expired or suspended package count against the custom field limit for your Salesforce edition. To fix this issue, reactivate your license or uninstall the package. |
| Data stored in the records associated with custom objects in managed packages. | Record data counts against your org’s data storage limit. |
