Upgrade a SKU
This article helps you upgrade from the Basic Tier (SKU) to Standard. Once you upgrade, you can't revert back to the Basic SKU without deleting and reconfiguring Bastion. Currently, this setting can be configured in the Azure portal only. For more information about features and SKUs, see Configuration settings.
Sign in to the Azure portal.
In the Azure portal, go to your Bastion host.
On the Configuration page, for Tier, select Standard.
You can add features at the same time you upgrade the SKU. You don't need to upgrade the SKU and then go back to add the features as a separate step.
Click Apply to apply changes. The bastion host will update. This takes about 10 minutes to complete.
