title: Transactional Replication from SQL Server 2008R2 to SQL Server 2017
body: <p>I wanted to ask about Your experience related to set up a Transactional replication between SQL SERVER 2008R2 (publisher) and SQL SERVER 2017 (subscriber).</p>
  <p>I know that this is not supported by Microsoft according to &quot;Transactional &amp; Snapshot Replication compatibility matrix&quot;, <a href="https://docs.microsoft.com/en-us/sql/relational-databases/replication/replication-backward-compatibility?view=sql-server-ver15" rel="nofollow noreferrer">in the docs</a>.</p>
  <p>But I set up this kind of transactional replication (2008R2 -&gt; 2017) on a few databases and it works without any errors. So the question is when or in what kind of situation (maybe some special type of configuration, user-defined data types...), this replication could stop to work or generate errors?</p>
