I am trying to migrate custom work item from "ABC" from one project 'x' org to another project in 'y' organisation using the VSTS sync migrator.
While migrating I get this error:
WorkItemRevisionReplayMigrationContext: ...the WITD named ABC is not in the list provided in the configuration.json under WorkItemTypeDefinitions. Add it to the list to enable migration of this work item type.
I was able to successfully migrate all other work items like user story, bug which already exist in ADO
Please get the latest version of Migration Tools for Azure DevOps from the website below:

And check whether you have created WIT "ABC" in 'y' organization.
