Exporting using migrator CLI broken for AWS/Azure Accounts #9752
Description
Severity
Blocking Customers from using the Migrator if they have setup any Account Types
Version
2025.3.11974 onwards.
Latest Version
I could reproduce the problem in the latest build
What happened?
If you have Accounts set up in Octopus, you will get an error when using the Data Export feature (Octopus Migrator).
The error will depend on if you have the account as a variable within a project or not.
If you have the account setup on the Accounts page but its not included in any project variables you will see an error such as:
Error: System.Exception: Unable to determine type to deserialize. AccountType AzureServicePrincipal does not map to a known type
If you have that same Account as a variable in a project you will see errors such as:
Newtonsoft.Json.JsonSerializationException: Invalid Variable Type AzureAccount.
I have tested this for an Azure Account and an AWS account. It doesnt seem to error with an OIDC or Google Cloud account in my testing.
Reproduction
- Create an AWS and Azure Account and save them.
- Try the Data Export from the Octopus Manager and see the errors.
- Add those same accounts as Project Variables - ensure they are of the 'Account' type.
- Try the data export and see different errors.

Workaround
The only workaround at the moment to use the Data Migrator would be to delete any AWS/Azure Accounts you have in Octopus (which is not something we would want to recommend to customers so we will see if we can resolve this issue quickly).
You can use the project export feature in the meantime if you need to export some projects across. I can confirm this does work as expected and brings the AWS and Azure accounts over on the export.
