You can directly apply a new Bitdefender Signature service. Your USG must have at least firmware version 4.31!
The following steps will help you activate your Bitdefender licenses and give you options to convert your linked or activated Kaspersky Signature licenses at once:
- Sign-in to myZyxel portal https://accounts.myzyxel.com
- Go to Service Management, click on Unlinked Licenses.
- Select your Bitdefender license and click the button link in the status column.
- In the pop-up dialog “Link Product”, choose the device from the dropdown list and click on Submit
- In the pop-up dialog “Convert Gateway Anti-Virus_Kaspersky Signature service”, click the button Convert to proceed.
Afterwards, myZyxel will convert the all Kaspersky licenses into the device to Bitdefender Signature immediately
