Before you convert an existing package to managed, alert any current installers that they must save their data:
  1. Export all the data from the previous, unmanaged version of the package.
  2. Uninstall the unmanaged package.
  3. Install the new managed version of the package.
  4. Import all the exported data into the new managed package.

    Note to installers: if you have made customizations to an installation of an unmanaged package, make a list of these customizations before uninstalling since you may want to implement them again.

    Note

To convert an unmanaged package into a managed package:
  1. Register a namespace.
  2. From Setup, enter Package Manager in the Quick Find box, then select Package Manager.
  3. Edit the package that you want to make managed, then select Managed.
