Migrating from VSTS (visualstudio.com) to Azure DevOps (dev.azure.com)

[chfe0113]

Hi
Some background before the question:

I have a site that was created a long time ago on VSTS (xxxxx.visualstudio.com) we setup at work and used Microsoft "Personal" accounts created with our enterprise email addresses to connect to it.

Fast Forward to 2023....our enterprise email is now tied to O365, and we can no longer make personal accounts with these email addresses. This limits anyone new in the company from accessing the repos/project/etc.

The solution is to use dev.azure.com which is able to use our O365 AAD email accounts. This works.

Now, I need a way to migrate all the work items/etc from the visualstudio.com site to the dev.azure.com site. I can clone the repos without issue. Looking into how to do this brought me to this site.

#1. Based on what I have read, this application should support this type of migration from VSTS to AzureDevOps, correct?
#2. I have ran the configuration and I am getting the error that i have found multiple others post about:

       Not all work items in scope contain a valid ReflectedWorkItemId Field!
       Microsoft.TeamFoundation.WorkItemTracking.Client.InvalidFieldValueException: Not all work items in scope contain a valid 
       ReflectedWorkItemId Field!

I have created the ReflectedWorkItemId field on all my worktypes on the processes in both the Source and Target but still continue to get this error. Before adding that field, the error said "The query references a field that does not exist.", so it seems to be finding now...

#3. Here is my config

Looking for any information to move forward with this, or if its even possible from VSTS to AzureDevOps.

Thank you!

Just after the Not all work items in scope contain a valid ReflectedWorkItemId Field! message ` it should list the work item types that do not have the field added.

Can you add your full log?
