class MigrateJiraToGem < ActiveRecord::Migration
DOWNTIME = true
DOWNTIME_REASON = <<-HEREDOC
Refactor all Jira services properties(serialized field) to use new jira-ruby gem.
There were properties on old Jira service that are not needed anymore after the
service refactoring: api_url, project_url, new_issue_url, issues_url.
We extract the new necessary some properties from old keys and delete them:
taking project_key from project_url and url from api_url
