Jan Provaznik 0fc9f9d3e7 Add version 4.2 to all existing migrations
DB schema generated by a migration may look different in
rails 4 and 5 (because rails 5 may use different default values).
For this reason it's important to explicitly set for which rails
version a migration was written for.

class MigrateJiraToGem < ActiveRecord::Migration[4.2]
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
