Import/Export

As the current image does not provide an efficient way to backup your projects, it is recommended to manually export your flow definition (as templates).

• Go to Nifi
• On the left, in the "Operate" box, click on the icon "Create Template", set a name and click on "Create"
  • Now, you have a template, saved in Nifi
• For exporting the template on your PC:
  • In the upper right, click on the hamburger icon, then click on "Templates" in the menu
  • In the list, click on the download icon to get it (it's a xml file)

For using a template:

• Go to Nifi
• Right click in the main page, click on "Upload template"
• Select the XML file containing the template definition
• Once the template has been loaded, you can add the template to your flows by clicking on the icon "Template"
