then i dump the database in 2.3 and start upgrade. following upgrade guide.

at the step of migrate the database

bundle exec rake db:migrate RAILS_ENV=production --trace

an error occured

```

$ bundle exec rake db:migrate RAILS_ENV=production --trace

```

i don't know why and what to do next

If i ignore the error msg and continue the upgrade steps , run the server

the production log

```

$ cat production.log
Started GET "/" for 127.0.0.1 at 2015-05-21 16:55:21 +0800

```

what should i do to solve the problem?
