At one point we were exploring having both sqlalchemy-migrate and<br>
alembic run, one after the other, so that we only need to create new<br>
migrations with alembic and do not need to change any of the existing<br>
migrations. Was that idea dropped?<br>

to my knowledge the idea wasn't dropped. If a project wants to implement that using the oslo.db system, that is fine, however from my POV I'd prefer to just port the SQLA-migrate files over and drop the migrate dependency altogether. Whether or not a project does the "run both" step as an interim step doesn't affect that effort very much.<div class="HOEnZb"><div class="h5"><br></div></div></blockquote><div><br></div><div>Hi Mike</div><div><br></div><div>Just a quick question: How would the alembic scripts know where to start the migration from if the current installation had been up until that</div><div>point been using migrate (I believe both alembic and migrate write to a small table what the current version is, would you look for that?)?</div><div><br></div><div>-Angus</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="HOEnZb"><div class="h5">
