Create a Salesforce DX Project from Existing Source

If you are already a Salesforce developer or ISV, you likely have existing source in a managed package in your packaging org or some application source in your sandbox or production org. Before you begin using Salesforce DX, retrieve the existing source and convert it to the source format.

If your current repo follows the directory structure that is created from a Metadata API retrieve, you can skip to converting the metadata format after you create a Salesforce DX project.

Tip

  1. Create a Salesforce DX project.
  2. Create a directory for the metadata retrieve. You can create this directory anywhere. 
    1mkdir mdapipkg
  3. Retrieve your metadata source.
