title: What happens to the Wiki of TFS 2018 when migrating to Azure DevOps Server 2019
body: <p>We are evaluating the migration from TFS 2018 to Azure DevOps 2019 Server.
  Unfortunately we don't understand what happen to the Wiki pages.</p>
  
  <p>In fact looks like that Azure DevOps 2019 uses Git based wikis while TFS 2018 was using a different approach.</p>
  
  <p>Are going to loose all articles or they will be migrated?
  We have both HTML and Markdown wiki articles.</p>
