Scheduled
Anticipated Impact: Potential for short interruption of customer instances and configuration portal during the window.
The Operations team will be installing a rolling software update. There is potential for short connectivity impact (approximately ~1-2 minutes) for each customer instance and the configuration portal while these components are updated. No other impact on service delivery is expected.
Tenant upgrades to 26.1.1 will be processed Tuesday, March 3rd through Thursday, March 5th. Upgrades will follow your assigned maintenance window, consistent with prior scheduled maintenances. Customers who have configured a preferred maintenance window in the FortiSASE portal will be upgraded during their selected hours. For details on maintenance window scheduling, see:
https://docs.fortinet.com/document/fortisase/latest/administration-guide/190872/appendix-e-monthly-maintenance
Mature to Feature Migration
Selected Mature instances will migrate to Feature the following week, Monday, March 9th through Friday, March 13th. Migrations will follow the same maintenance window scheduling as tenant upgrades, and each customer instance will only be impacted once during the week. Affected customers will see a migration notice upon logging into the FortiSASE portal. Customers who prefer to control the timing of their migration can self-initiate the process through the portal in advance.
