Promblem in gitlab-ctl reconfigure

I upgrade the gitlab version 8.7.9 to 11.1
When I gitlab-ctl reconfigure ,encounter some error:

There was an error running gitlab-ctl reconfigure:

bash[migrate gitlab-rails database] (gitlab::database_migrations line 49) had an error: Mixlib::ShellOut::ShellCommandFailed: Expected process to exit with [0], but received ‘1’
