All SPOCs and Technical Contacts:
The CWDS Infrastructure team and IBM will be upgrading all of the CWS/CMS gateway servers throughout the state from Windows 2016 to Windows 2019. Due to the redundancy within the network, there is no anticipated impact or performance issue for the CWS/CMS user. This upgrade needs to occur on the gateway servers before Windows 2016 goes out of support by Microsoft in January 2027.
To minimize any potential impacts, only one gateway server will be upgraded at a time. Also, gaps have been scheduled between the upgrades to allow time to analyze the impact to the remaining servers within the system. All upgrades will be performed outside of normal business hours.
The upgrades will be performed through four separate phases. For the first phase, one Co-Existent County gateway server will be upgraded on Tuesday, June 24, 2025, the second gateway server on Thursday, June 26, 2025, and the third gateway server on Tuesday, July 1, 2025. The first Dedicated County gateway server will be upgraded on Thursday, July 3, 2025.
There will be a gap in the upgrade schedule to allow the Infrastructure team and IBM to review the impact of the first phase of upgrades. The remaining gateway servers will be upgraded in three more phases, currently planned for September, October, and November 2025.
Communications for the three remaining phases will be sent prior to the upgrades.
