title: Firebird upgrade from 2.1.3 to 2.5?
body: <p>Is there a list anywhere or best practice instructions for update firebird databases from one version to another (in my case 2.1.3 to 2.5.2)?</p>
  
  <p>I have seen backup and restore mentioned. I have updated from 1.5 to 2.1 in the past but that just worked i.e. I just installed the new firebird version, however I aware that this was probably just luck.</p>
  
  <p>Regards</p>
