### Conditional migrations
@ -34,13 +38,11 @@ Arising from [Capistrano/Rails issue #199](https://github.com/capistrano/rails/i
A frequent issue on deploy are slow migrations which involve downtime. In this case, you often want to run the migrations conditionally, where the main deploy doesn't run them, but you can do so manually at a better point. To do so, you could put the following in your `Capfile`:
```ruby
if ENV['RUN_MIGRATIONS'].present?
require 'capistrano/rails/migrations'
end
require 'capistrano/rails/migrations' if ENV['RUN_MIGRATIONS']
```
Now the migrations do not run by default, but they will run with the following command:
```bash
RUN_MIGRATIONS=true bundle exec cap production deploy:migrate
RUN_MIGRATIONS=1 bundle exec cap production deploy:migrate
```
