When you purchase new entitlements, Cortex XSIAM automatically applies them to your tenant through a seamless upgrade process. If any downtime is required, you’ll receive advance notice and can choose a convenient time to proceed with the upgrade.
A banner notifies you that an upgrade is scheduled. To see details of the upgrade schedule, click **view upgrade details**. You can continue with the update schedule, or take one of the following actions:
* To upgrade immediately, click **Upgrade now**.
* To schedule an upgrade, select a start date and time from the calendar.
Keep in mind the following during the upgrade process:
* The gateway may experience up to two hours of downtime during the installation.
* The upgrade will occur automatically on the scheduled time and date unless you change it. The product will also display a banner 24-hours before the upgrade occurs.
* The development tenant associated with the upgraded production tenant will also be upgraded.
* Pairing Prisma Cloud Compute with Cortex XSIAM is not supported in XSIAM 3.X versions.
