title: Is there any way to keep the original Id when migrating using Azure DevOps Migration Tools?
body: <p>I'm using the Azure DevOps Migration Tools to migrate our work items from one organisation to another.</p>
  <p>The ReflectedWorkItemIDFieldName fills in ID_old with values like <a href="https://dev.azure.com/myOldSite/MyProject/_workitems/edit/99" rel="nofollow noreferrer">https://dev.azure.com/myOldSite/MyProject/_workitems/edit/99</a></p>
  <p>I'd like to be able to migrate Id=xx from myOldSite to Id=xx from myNewSite, but I'm not able to find a way to migrate the Id number from the old to the new Azure DevOps systems.</p>
  <p>Any thoughts?</p>
  <p>My configuration.json is</p>
