First-Generation Managed Packages
Managed packages are used by Salesforce partners to distribute and sell applications to
customers. Using AppExchange and the License Management Application (LMA), developers can sell
and manage user-based licenses to their app. Managed packages are upgradeable.
Building a new app? Have you considered using second-generation managed packages? Flexible versioning and the ability to share a namespace across packages are just two reasons why developers love creating second-generation managed packages. We think you’d love it, too.

Why Switch to Second-Generation Managed Packaging?
You’ve been using first-generation managed packages to develop your apps, so you’re probably pretty familiar with what works well, and what’s a bit more painful than you’d like. And no doubt, you’re aware that second-generation managed packages is our newer technology, but maybe you aren’t so sure why switching to second-generation managed packaging (managed 2GP) will improve your package development experience. So let’s talk about that. -
Move to 2GP: Migrate Your Managed Packages with Ease
Are you still using first-generation managed packaging (1GP) for your package development work? If so, you're not alone. Many ISVs like you are looking to move to second-generation managed packaging (2GP) and take advantage of its many benefits. -
Register a Namespace for a First-Generation Managed Package
A namespace is a one to 15-character alphanumeric identifier that distinguishes your package and its contents from packages of other developers on AppExchange. Namespace prefixes are case-insensitive. For example, ABC and abc aren’t recognized as unique. Your namespace must be globally unique across all Salesforce orgs. -
Create a First-Generation Managed Package Using a UI
If your goal is to build an app and distribute it on AppExchange, you use managed packages to do both. Packaging is the container that you fill with metadata, and it holds the set of related features, customizations, and schema that make up your app. A package can include many different metadata components, and you can package a single component, an app, or library. -
Create a First-Generation Managed Package using Salesforce DX
If you’re an ISV, you want to build a managed package. A managed package is a bundle of components that make up an application or piece of functionality. A managed package is a great way to release an app for sale and to support licensing your features. You can protect intellectual property because the source code of many components isn’t available through the package. You can also roll out upgrades to the package. -
Components Available in First-Generation Managed Packages
Each metadata component that you include in a first-generation managed package has certain rules that determine its behavior in a subscriber org. Manageability rules determine whether you, or the subscriber, can edit or remove components after the package version is created and installed. -
