I am playing around with the force:org:clone command(which is in BETA) but can't get it to work.

Here's the command I put together: sfdx force:org:clone -u [email protected] -a FULL_CLONE -t sandbox

The error I get is: To indicate which sandbox org you want to clone, specify SourceSandboxName in a definition file or as a command line argument.

I looked at all the arguments that are listed for the command and don't see anything related to SourceSandboxName. Isn't the username making it clear enough which sandbox I am trying to clone?

In addition it appears that the documentation is incorrect, if you take a look at their example its referencing sfdx force:org:create.

Here's a link to the documentation: https://developer.salesforce.com/docs/atlas.en-us.sfdx_cli_reference.meta/sfdx_cli_reference/cli_reference_force_org.htm

We got an answer on social media:

The docs for the sandbox operations and the help topic fixes are scheduled to be published today. -u needs to point to the org with sandbox licenses ie the prod org. SourceSandboxName is a field in the definition file, not the command and should reference sandbox being cloned.

The appropriate command will look like this:

sfdx force:org:clone -f config/cloned-sandbox.json -u prod-org -t sandbox

The docs should reflect this soon.

  • What values we should have in the cloned-sandbox.json file, like key=value pair @sfdcfox Commented May 27, 2020 at 16:18

    @YaswanthTikkisetti It's a JSON file, so something like { "SourceSandboxName": "sbname" } You can also just use SourceSandboxName=sbname on the command line.

Hello below is a command used to clone a developer org. I will explain each parameter.

sfdx force:org:clone -t sandbox SandboxName=DevSbx1 SourceSandboxName=jnbanksan -u prod -a MyDevSandbox
  1. -t specifies its a sandbox to be created
  2. SandboxName - is the actual JSON field name in the definition field schema, which denotes your sandbox name.
  3. -u is the authenticated prod instance,
  4. -a is the alias to reference this newly created sandbox
  5. SourceSandboxName is the actual existing org name you wish to clone not the org alias.
