Does syncing data from Production to Sandbox overwrite changes to the Sandbox?

[Monty]

Here's my environment:

• Production:
  • 2 Software projects
• Sandbox:
  • Synced previously
  • 2 Software projects
    • No changes made.
  • 1 New Service Management Project
    • Many changes to request types, issue types, workflows, etc

We are in the process of creating a new service management project and testing changes before lifting it up to production.  If we sync production to sandbox, will it overwrite the changes that we've made to the service management project?

I want to be able to test things like moving tickets from one project to another, but we want to be able to refresh the data from the production projects so that we can test different scenarios.

In the documentation:

I'm concerned about this statement:

When you copy data from your production environment to its sandbox, we’ll replace the existing data in your sandbox with the newly copied data. Every new data copy will overwrite any existing data in your sandbox.

The way that I interpret this is that if an issue exists in both environments, syncing will overwrite any changes to the that, but it won't overwrite any data that isn't in production.  I'm just worried that all the work we've put into configuring the sandbox will get erased and want to double and triple check that that won't happen.

For the full data copy yes it will override existing data, however, you can use the new selective copying feature to select specific projects only to copy over. More details here

That is the same link that I posted in my original post. 

I guess that answers my question though. It looks like I can copy just the projects that I want and it won't override the data that I've configured in the project that we created in the sandbox.

I guess I just need to be careful if any settings from the original projects share settings with the new project.

If you're trying to sync configuration data and want to be more selective, you can try out Salto. We allow full granularity so you can cherry-pick which configuration elements to bring over to your sandbox.
