title: Akeneo 2.1.4 : How can I change an attribute type?
body: <p>I have an attribute of type <code>pim_catalog_number</code>, but I need to change this to <code>pim_catalog_simpleselect</code>. I cannot change this in Akeneo and if I try to overwrite it by importing a new attributes-file I get the notice that I am not allowed to change the type.</p>
  
  <p>But I have a scenario where I need to do this. So what's the proper way to do this? I can imagine doing some direct SQL queries, but what are the consequences of changing the type directly in the database?</p>
