My old Azure DevOps Organization has multiple projects and I'd like to export and import the Azure DevOps Project between the organizations, especially the Work Items in Boards.
I came across the Microsoft document - https://learn.microsoft.com/en-us/rest/api/azure/devops/wit/work-items/create?view=azure-devops-rest-7.1&tabs=HTTP
Do we have any reference projects that uses Azure DevOps REST APIs to export and import the Azure DevOps Project?
No, there doesn't have a built-in feature to achieve your requirement.
If you use F12 to capture the network traffic you will find the related request structure like this:
CSV file was not been uploaded directly, it was firstly been parsed and then put it into the request.
It is obviously unrealistic to use such a request because it is too complicated.
A feasible solution is to use the REST API to get the workitems information, and then save this information to a CSV file. Then read the CSV file information and fill it into the REST API of Create Workitems.
