Upgrade Procedure

This procedure assumes that your Services Appliance is already installed on a network.

Note: Data backup is recommended prior to upgrading FortiWLM.

Upgrading via GUI

The following procedure will guide you through the steps to upgrade your server from WebUI.

1. In the FortiWLM GUI, go to Administration > WLM Upgrade. By default, this page lists all the images copied to the server.
2. To upgrade your server to a different version than the ones listed, click Add to open the file selector window.
   Select the image file from your computer or a network folder and click UPLOAD.
3. After the upload is complete, select the version to install and click INSTALL to being the upgrade process.

Note: During the upgrade process, do not click refresh or perform any operations on the server.

After the upgrade is complete, click Go to return to server operations.

• For a full upgrade, the server will restart after the upgrade process and return the page to server login prompt.

• For patch upgrade, the server will restart the process and return to the dashboard.

Upgrading via CLI

To upgrade a Services Appliance, perform the following steps:

1. Perform a complete Network Manager backup and copy the backup file to an external location. Use this if you run into a problem (Instructions for backing up the file can be found in the Maintenance chapter of the Network Manager User Guide.)
2. If you have SAM installed, disable all scheduled tests by performing the following steps:
   1. Select Service Assurance.
   2. From the left panel, select Configure > Tests > Scheduled Tests.
   3. Select the Disable All option and click OK continue.
3. Access the Services Appliance through SSH, using the administrative privilege.
4. If your appliance flash already contains three images, remove one of the older images using the delete flash: <version number> command.
5. Copy the file from the SCP server to your FortiWLM using the copy command, for example, sa# copy scp://user:password@server/path/forti-wlm-<releaseVersion>-rpm.tar.fwlm<space>.
6. Confirm the successful transfer of the image by displaying the current flash images using the sh flash command - sa# sh flash 8.6-6build-5.
7. Upgrade the FortiWLM - sa# upgrade nms-server <Version>.

   This process installs new binaries and upgrades the stored data to the latest version. This process may take a few minutes and at the end of the upgrade the services appliance restarts. The time taken to upgrade, depends on the size of the data available on the FortiWLM.

8. Type the following command to confirm, if the installed software version is 8.6.6.
   sa# sh nms.

If the upgrade displays the "image integrity error," the FortiWLM image has been corrupted while uploading to FortiWLM. Upload the new image again to the FortiWLM and retry the upgrade. You can ignore the Security warning "Installing an unsigned upgrade package!" displayed by the upgrade command.
