# Upgrading Original iSG Display to Support HA to the Latest Version

## <mark style="color:blue;">IMPORTANT:</mark>

* <mark style="color:blue;">This guide is for original iSG Display only.</mark>
* <mark style="color:blue;">This guide is for users want to keep their previous iSG and HA settings. For new users without need of data backup and restoration, please just read part 3 and 5.</mark>

### 1. Back Up iSG

Go to **iSG Settings** > **iSG Firmware / Backup** > **Backup iSG**, and save the backup file to your USB drive.

### 2. Back Up Home Assistant

In **iSG Home Assistant**, go to **Settings** > **System** > **Backup**, then save the backup file to your USB drive.

For detailed steps, please refer to the [iSG and Home Assistant Backup Guide](https://kb.linknlink.com/isg/settings/backup).

### 3. Flash iSG image from 32-bit to 64-bit

Flash the iSG image to the 64-bit version.

Refer to the [<mark style="color:blue;">Flashing iSG System Image</mark>](https://kb.linknlink.com/isg/settings/firmware-updates/flashing-isg-system-image) guide for instructions.

### 4. Restore iSG

After flashing and restarting iSG, you'll be prompted to sign in. **Do not sign in yet.** Instead, click **Restore** and select your iSG backup file from the USB drive.

### 5. Setup Wizard

After restoration, iSG will begin initializing all configurations. Most setups are completed automatically without user intervention.&#x20;

The only step requiring your input is the Zigbee setup, where you’ll choose the operating mode for the Zigbee radio (**Z2M** is highly recommended). If you select Z2M mode, please refer to the article [Firmware Update > Zigbee Firmware (USB Dongle)](https://kb.linknlink.com/isg/settings/firmware-updates/isg-zigbee-dongle) to update the firmware on PC.&#x20;

**IMPORTANT:** The Zigbee radio firmware update is irreversible if you choose **Z2M mode**. Once applied, it cannot be changed to **Direct Mode**.

Afterward, plug in the dongle and proceed with the auto-configuration of the Zigbee profile.

### 6. Restore HA

After all configurations are complete, navigate to **Settings > Local HA > Restore HA**. You’ll be taken to iSG’s file manager. Select the appropriate HA backup file, and iSG will restore your built-in Home Assistant settings to their previous state.

### 7. Re-Configure HA Token

After restoring your HA backup, the local HA status may remain in **Starting**. This is because the current HA instance token differs from what’s in your backup, preventing authentication. To resolve this, go to **Settings > Local HA > Start Initialization.**

follow the on-screen instructions to copy the token from the current HA instance.

Then, paste it into iSG’s HA Token verification page to complete the verification.

The wizard will also guide you through reconfiguring the MQTT broker. If you choose to use the default settings, simply click **Next** to proceed and complete the setup.
