On my development box, I find myself needing multiple instances. One site I’m importing is on `stable`, others use importers that I am developing. Right now what I do is when switching jobs, I switch branches in git and run a script that does

```bash
RAILS_ENV=development
export RAILS_ENV
RAILS_ENV=development bundle exec rake db:drop db:create db:migrate
bundle exec rake admin:create

```

It’s really annoying when I’ve, say, run an importer that takes several hours and then want to run it again with updated input (and not have to re-import the whole thing).

Is there something different I should be doing? Perhaps I should run separate instances with Vagrant? Contrive to tell Discourse to use a different database for each different job?

Or am I doing the Right Thing?
