Benefits of the Upgrade/Downgrade Feature:

• Flexibility in Operations: No longer do you need to be stuck with one SKU. Easily switch between Standard and Premium SKUs based on your evolving requirements.
• Minimized Business Interruptions: It's recommended to perform the upgrade/downgrade during off-peak hours, ensuring minimal disruption to regular operations.

Upgrading Process Insights:

• Policy Attachments: During the upgrade, you can opt for either an existing Premium Policy or a Standard Policy. For those with existing Standard policies, the system can auto-duplicate, elevate it to Premium, and attach it to the new Premium Firewall.
• Multiple Access Points: Users have the flexibility to access this feature via different platforms, be it the Azure portal, PowerShell, or even Terraform. Adjusting the sku_tier attribute facilitates the upgrade/downgrade process.

Limitations to Note:

As of now, this capability doesn't extend to Azure Firewall's Basic SKU.

Conclusion:

This enhanced feature in Azure Firewall bolsters user flexibility, making SKU transitions smoother than ever. As the digital landscape becomes more dynamic, such updates empower businesses to adjust their defenses accordingly.
