</span>I possibly shouldn't comment at all, as I don't know the history, and<br>
wasn't around when the fundamental design decisions here were being made.<br>
<br>
However, it seems a shame to me that this was done in a way that needs a<br>
DB migration at all. (And I would have thought it possible for the<br>
default pluggable IPAM driver to use the same DB state as the<br>
non-pluggable IPAM backend, given that it is delivering the same<br>
semantics.) Without that, I believe it should be a no-brainer to switch<br>
unconditionally to the pluggable IPAM backend.<br></blockquote><div><br></div><div>This was indeed the first implementation attempt that we made, but it failed spectacularly as we wrestled with different foreign key relationships in the original and new model.</div><div>Pavel has all the details, but after careful considerations we decided to adopt a specular model with different db tables.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
