Upgrade Nintex Forms

This topic describes how to upgrade Nintex Forms only, from Nintex Forms 2016 or Nintex Forms 2019 to Nintex Forms Subscription Edition.

Note: If you are upgrading Nintex Workflow as well as Nintex Forms, upgrade both at the same time.

To upgrade Nintex Forms only

  1. If Nintex Live is in use, note the Live ID: On the Central Administration Home page, click Nintex Live Management and then click Connection Settings.  

    This Live ID will need to be specified in the SharePoint Subscription Edition environment.

  2. If you are upgrading from SharePoint 2016 and plan to continue using external forms with Nintex Forms Subscription Edition:

    1. Disable the following external forms services on the SharePoint 2016 environment:
      • Nintex External Forms Manager
      • Nintex External Forms Synchronisation

      Note: This step applies when you plan to continue use of external forms with Nintex Forms Subscription Edition. These services must be disabled on your Nintex Forms 2016 environment before activating external forms on the new environment. Disabling the services prevents external forms from going to the previous environment. External forms were formerly known as Nintex Live forms.

  3. Back up the following databases on your previous SharePoint environment using Microsoft SQL Server Management Studio.

    • SharePoint content databases

      Example: "WSS_Content"

    • Nintex Forms databases

      Example: "NintexForms"

  4. Install Nintex Forms Subscription Edition by running the installer.

    For instructions on running the installer, installing optional features (such as Enterprise Edition), and importing the license, see the installation guide.

  5. On your SharePoint Subscription Edition environment, restore the backed up databases using Microsoft SQL Server Management Studio.

    1. Attach your SharePoint content database using the Mount-SPContentDatabase PowerShell command per Microsoft guidance.

      Example SharePoint content database: "WSS_Content"

    2. Restore the Nintex Forms databases.

      Example Nintex Forms database: "NintexForms"

      1. On the Central Administration Home page, click Nintex Administration and then click Database management under Licensing and setup.
      2. Under Nintex Forms, under Configuration database, click Manage and then enter the restored Nintex Forms databases.
  6. Restore the Live ID noted at the beginning of this procedure.

    For instructions, see Restore the external connection end point ID.

  7. Activate Nintex Forms on all required web applications.
    1. On the Central Administration Home page, click Application Management and then click Manage web applications.

    2. On the Web applications page, select the row corresponding to the web application.

      For example, select the row for "SharePoint - 80." 

    3. Click Manage features.
    4. In the Manage Web Application Features dialog box, to the right of Nintex Forms, click Activate and then click OK to close the dialog box.
    5. Repeat as needed for additional web applications.
  8. (Optional.) Enable external mobile access.
    1. On the Central Administration Home page, click Nintex Administration and then click Remote mobile access under Forms environment.
    2. Select Enabled for Enable External Mobile Access.
