What is a Managed Package and Unmanaged package?
Managed packages are AppExchange packages that can be upgraded in the installer's organization. They differ from unmanaged packages in that some components are locked, allowing the upgrade process. Unmanaged packages do not include locked components and can not be upgraded.
Before the Winter '07 release, all packages were unmanaged. Now, you can convert an unmanaged package to managed to ensure your installed users get upgrades.
Unmanaged Package Managed Package
What Completely Editable by Developer and Installer
Can NOT be upgraded Certain Components are locked
No Destructive Changes to app
Supports Seamless Upgrading
Supports LMA for Managing Installs
When to Use 1:1 Distribution
Extensive Modification Required 1:Many Distribution
Commerical Intent
Foresee Upgrades
Editions Supported All Editions can create Unmanaged Packages ONLY Developer Edition can create Managed Packages
Managed packages differ from unmanaged packages in many other ways. Before creating managed packages, here are a few things to consider:
You must use a Developer Edition organization to create and work with a managed package.
A Developer Edition organization can contain a single managed package and many unmanaged packages.
You must register a Namespace Prefix - A Namespace Prefix is a series of characters prefixed to your Custom Objects and Fields to prevent conflict when installed in another salesforce.com org.
When you release a managed package, meaning it is uploaded with the Managed - Released option selected, the properties of its components change to prevent developers and installers from making harmful changes. For a list of each package component type and their properties, see Properties of Managed Packages. If you do not want to offer upgrades to your package, consider keeping it unmanaged.
If you plan to release your app as a Managed Package, please read out guide on Planning the Release of Managed Packages
If you already have a Unmanaged Package and you'd like to convert it to Managed, please review the following: Converting Unmanaged Packages to Managed
Now that you understand the difference and benefits of each type of package, let's see how easy it is to make your Unmanaged package from above into a Managed Package.
