The shared SQL Server production data mart system IOWASQLDMHOST3 will be upgraded from SQL Server 2016 to SQL Server 2019. The new SQL Server 2019 system will have network connectivity restricted to ITS data centers and, on request, static IP addresses on wired campus building machines. These SQL Server databases will no longer be open to campus wireless or VPN.

Additionally, some clients may need to update their connection strings to use the fully qualified domain name (FQDN) of the database server (e.g. IOWASQLDMHOST3.iowa.uiowa.edu). For more information about this migration, please review S

During the maintenance window, Top Hat will be unavailable and visitors to app.tophat.com will see a maintenance page.

As part of our ongoing efforts to reduce packet loss and latency within the datacenter network, we are replacing two old optics that currently increment FCS errors causing re-transmissions and packet loss. These interfaces are critical as they connect the legacy environment to the new fabric at ITF.

1. Replace optic in rtr-itf-2-research@Eth10/6
2. Replace optic in rtr-itf-1-production@7/4

While unlikely, there is the possibility for a brief blip in service for each of these changes.

We will also decommission an old Fex on lc-30, allowing us to free up space for more device migrations.

The Jamf service will be upgraded to version 11.11.1. There should be no interruption of services to our clients.

During the maintenance window some wireless devices may experience connectivity issues for short periods of time.
