Hello!
Unfortunately, at the moment there is no built-in feature to connect different Orchestrator instances to each other.
But there are a few tools that may be helpful in your case:
- PowerShell cmdlet library that, among other operations, can make it easier to copy Packages (and other entities) between Orchestrator instances: GitHub - UiPath/orchestrator-powershell: UiPath Orchestrator PowerShell cmdlet library
- UiPath Studio project that allows bulk operations on entities (including Packages), so that you can download the selected Packages from one environment and upload to another: Orchestrator Manager - RPA Component | UiPath Marketplace. This video shows how to do something similar for Assets, but the same idea applies to Packages: Migration of Assets with Orchestrator Manager - YouTube
- Depending on what you are doing and using, this Jenkis plugin might also be helpful: Jenkins Plugin for UiPath - General Availability - RPA Component | UiPath Marketplace
