# Test Your Converted Managed 2GP Package

Before you migrate your first subscribers, we strongly recommend you install your newly converted managed 2GP package into a new scratch org and test its functionality. If you prefer, you can also install the converted package in a sandbox, or developer edition org.

1. Create a scratch org. When creating your scratch org, be sure to include a scratch org definition file that includes any Salesforce features that your package depends on.

   ```nolang
   sf org create scratch --target-dev-hub MyHub --definition-file config/project-scratch-def.json
   ```

2. Migrate the converted package.

   To verify the 04t ID of the converted package, run `sf package version list` and review the command output. Then run the package install command and specify the 04t ID. In this scenario, the package version is being migrated, not installed.

   Example:

   ```nolang
   sf package install --package 04t...
   ```

   Next, explore your package and test its functionality. Make sure everything is operating as expected. Note that the converted package is a beta version.

## Next Steps

During phase one you can convert your 1GP package, install the converted package in a scratch org, and try out package migration by using packages that are installed in scratch orgs. By testing these steps in a scratch org first, you can understand how package migration works, before migrating packages used by active customers.
