Hello,

The problem I am having is that we are currently migrating our projects from one server to another to move development in-house.
When I go to import the .json file using octo.exe, I get the exception:

“Handshake successful. Octopus version: 3.3.24; API version: 3.0.0

I have edited the .json file and so all the variables reference the correct environment and machine. I thought this would solve the problem but apparently not. I should also point out that the server that the project was exported from was using v3.3.0 whereas the server we’re trying to import to is using v3.3.24. I can’t find any documentation on what could be causing this error, so any help would be greatly appreciated.

Hi Cale,

Thanks for getting in touch. I think it’s failing at the following line of code (octo.exe is open source so it’s full source is available on GitHub). https://github.com/OctopusDeploy/Octo.exe/blob/master/source/Octopus.Cli/Importers/ProjectImporter.cs#L412

It’s failing to find an environment ID associated with one of the deployment process steps (actions). I would suggest double-checking the environment IDs to ensure the ones listed in the JSON file match the target server. In this case, it shouldn’t matter that the two servers are different versions.

That said, I’d like to mention that we have a better solution for import/export coming in Octopus 3.4. We’ve enhanced our migrator to add support to import/export individual projects and it’s far more robust than the current solution in octo.exe. This is coming soon so I’d recommend keeping it in mind when you’re ready to upgrade to the latest version.

Let me know how you go.

Hi Rob,

You are correct. One of the actions referenced an environment that no longer exists. I feel pretty silly for missing that haha.

Thanks again for your time.

No worries. It’s great to hear you got it working.

Happy deploying!
