Greetings from Eversource IT! You’re receiving this email because you are a trading partner with existing file transfer integrations with the EDI/BizManager application. Please review the below important information regarding the BizManager Upgrade Project’s Production Go-Live:

• The BizManager Upgrade team is scheduled to perform Go-Live activities beginning 3:00AM EST on Saturday, 10/24/2026, lasting through, at the latest, Monday 10/26/2026 at 2:00AM EST. 
• As BizManager is the central middleware IT application that delivers data files to all the tools, applications, and resources needed for us to perform our jobs effectively – it’s critical that you notify your business partners, at Eversource or otherwise, to either pause file transfers or expect file failures during this maintenance window.
• For critical files, begin preparing workarounds via alternative security-approved file transfer methods.
• The entire BizManager application will be down effective 3:00 AM EST on 10/24, and the outage will last until the cutover is complete.
  • WHAT THIS MEANS:
    • All inbound files destined for Eversource BizManager during this window will FAIL
    • BizManager will be incapable of transmitting ANY files outbound to any trading partner or system, internal or external
    • All monitoring and email alerts generated by BizManager will cease functioning
    • The legacy BizManager servers will be unreachable
    • The URL slinkprd.eversource.com and Network ports 443, 2022, 20022 will be unreachable
    • All SFTP and NAESB connections will be shut down
• The BizManager Upgrade Hypercare team is tracking an extensive list of anticipated file failures. Immediately following the upgrade activity, a large-scale reconciliation effort will begin to process all failed files.
• TO REITERATE: ALL TRADING PARTNERS SHOULD PREPARE FOR THIS OUTAGE.
  • Notify your business partners, whether they’re at Eversource or external to the company, to either PAUSE file transfer activities or expect file failures during this window of time.
  • For critical files that cannot wait to be reprocessed, prepare workarounds via alternative security-approved file transfer methods
  • Secure standby resources for the time period of 10/26-11/6 to assist the BizManager team with verifying failed file reprocessing in case we contact you
• Do you need to make any changes as part of the upgrade?
  • At this time, there should be NO changes required of any internal/external trading partner that has preexisting connections with BizManager
  • This cutover was designed by the project team to be minimally invasive to trading partners, with the sole exception of this weekend outage.
  • No changes are being made to file transfer integration configurations
  • No changes are being made to EDI maps
  • No changes to IP addresses, DNS hostnames, firewall rules, or network ports
  • Once application services come back up and the upgrade activity is complete, files should flow normally with no manual intervention.
• You can expect weekly reminders of the above information from now until Go-Live

Thank you for your partnership! We look forward to a successful implementation.

Sincerely,

Eversource IT – BizManager Upgrade Project Team
