 ## CSV file format
 
-Sample CSV file data: 
-
-CSV files must contain a header row where the first column header is `title` and the second is `description`.
-If additional columns are present, they will be ignored.
-
-### Header row
-
-CSV files must contain a header row beginning with at least two columns, `title` and
-`description`, in that order. If additional columns are present, they will be ignored.
-
-### Separators
-
-The column separator is automatically detected from the header row. Supported separator
-characters are: commas (`,`), semicolons (`;`), and tabs (`\t`).
-
-The row separator can be either `CRLF` or `LF`.
-
-### Quote character
-
-The double-quote (`"`) character is used to quote fields, enabling the use of the column
-separator within a field (see the third line in the [sample CSV](#csv-file-format)).
-To insert a double-quote (`"`) within a quoted field, use two double-quote characters
-in succession, i.e. `""`.
-
-### Data rows
-
-After the header row, succeeding rows must follow the same column order. The issue
-title is required while the description is optional.
-
-### File size
-
-The limit depends on the configuration value of Max Attachment Size for the GitLab instance.

+### Moving Issues in Bulk
+
+If you have advanced technical skills you can also bulk move all the issues from one project to another in the rails console. The below script will move all the issues from one project to another that are not in status **closed**.
+
+To access rails console run `sudo gitlab-rails console` on the GitLab server and run the below script. Please be sure to change **project**, **admin_user** and **target_project** to your values. We do also recommend [creating a backup](https://docs.gitlab.com/ee/raketasks/backup_restore.html#creating-a-backup-of-the-gitlab-system) before attempting any changes in the console.
+
+```ruby
+project = Project.find_by_full_path('full path of the project where issues are moved from')
+issues = project.issues
+admin_user = User.find_by_username('username of admin user') # make sure user has permissions to move the issues
+target_project = Project.find_by_full_path('full path of target project where issues moved to')
+
+issues.each do |issue|
+   if issue.state != "closed" && issue.moved_to.nil?
