YouTrack to Azure DevOps issue migration

This project contains a script for migrating issues from YouTrack to Azure DevOps Boards. It can migrate issues from a given YouTrack project to a given Azure DevOps project. It supports migration of comments, attachments, and custom fields.

Example usage

All interfacing with Azure DevOps requires a personal access token granting read+write access to work items, and which we refer to as pat below:

from migrator import Migrator, SetFieldOperation

pat = 'wz13hy65okghxfuodbvk3tmkilefxnx6gret04sl1m0didiocept'  # Placeholder: Replace with your own PAT
yt_base = "https://my-youtrack-instance"
ado_organization = "https://dev.azure.com/organization-name"
ado_project = "project-name"
migrator = Migrator(pat, yt_base, ado_organization, ado_project)

With this, you may want to first get a list of available custom fields on a given YouTrack issue, say AB-123:

print(migrator.custom_fields('AB-123'))

These custom fields can then be used to define how to migrate a particular issue or YouTrack project; for instance, to move YouTrack fields 'Priority' and 'Estimation' to Azure DevOps fields 'Task Priority', 'Estimation', define a handler through

def custom_field_handler(fields):
    priority = fields["Priority"].get("name", "")
    yield SetFieldOperation("Task Priority", priority, False)

    estimation = fields["Estimation"].get("presentation", "")
    yield SetFieldOperation("Estimation", estimation, False)

Here, the keys 'name' and 'presentation' depend on the type of custom field and can be read from the output of migrator.custom_fields above.

Note that when using "Task" as work item type in Azure DevOps Boards, some fields, such as System.State and System.Reason can only be set after the work item has been created; for such fields, use True for the third parameter above.

With this, we can migrate a particular issue through

migrator.migrate_issue('AB-123', custom_field_handler)

or an entire project through

migrator.migrate_project('AB', custom_field_handler, issue_count_upper_limit=50000)

where here, number_of_issues is simply any number greater than the number of issues in the project.
