Migration of Cisco Identity Services Engine hosts from VMware to Hyper V Mar `5`, `2027` `00:00` - Jun `10`, `2027` `01:00` PDT

From Friday, March 5 through Thursday, March 31, Cisco Identity Services Engine virtual hosts will be migrated from VMware to the Hyper V virtualization platform. The migration will be completed in phases by moving one ISE node at a time to maintain stability and service availability across the deployment. Each node will be temporarily removed from the F5 load balancing pool, migrated to Hyper V, validated for proper operation and database synchronization, and then returned to service before proceeding to the next node. The remaining ISE nodes and secondary datacenter will remain active during the process, allowing authentication services to continue operating while the migration is completed. The change aligns the environment with the current Hyper V infrastructure while maintaining operational continuity for the ISE platform.

Sep 3, 07:00 PDT

In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Sep 3, 06:00 PDT

Scheduled - ITS has scheduled the following maintenance:

When: Thursday, September 3 from 6:00 - 7:00 a.m. PT

Message: On Thursday, September 3 from 6:00 - 7:00 a.m. PT, IT Services will be performing the final cutover of ResNet AP & WLC management routing to resnet-swv-9600. A brief interruption to wireless service is expected throughout all ResNet locations during this window, likely under a minute, as routing shifts from the campus cores to resnet-swv-9600. In the unlikely event some APs need to re-establish their connection to the controller, this could take a few additional minutes to fully resolve. This does NOT affect ResNet Admin and Dining. This is a routine failover — no AP or WLC configuration changes are needed, and gateway IPs do not change.

Please contact ITS Service Desk at (858)246-HELP(4357) or servicedesk@ucsd.edu if you have any questions or concerns.
