Hold planned upgrades and contact Technical Support immediately for affected sites already upgraded. ## Potentially affected Sites planning or completing the listed ACC 7.14.44/7.14.46 and Unity 8.7.x/8.8.0.x upgrade paths. The notice also directs broader holds on planned ACC 7 upgrades to ACC 7.14.46.4 or Unity 8.8.x. ## DSE recommendation Pause affected upgrades, confirm each site's upgrade history, and contact Avigilon Technical Support immediately for any site already upgraded from an affected version. ## Article Put affected upgrades on hold. If your site has already upgraded from an affected version, contact [Avigilon Technical Support](https://www.avigilon.com/support/help) immediately, even if the system appears to be operating normally. Motorola Solutions technical notice MTN-0168-26, issued September 2, 2026, warns that an affected system can run normally for weeks before routine log cleanup triggers repeated server crashes. The potential data loss includes event metadata, saved bookmarks, and protected videos. Avigilon rates the notice High severity. ## Source facts and affected upgrade paths [MTN-0168-26](https://docs.avigilon.com/bundle/global-mtn-0168-26/) identifies these upgrade paths. ACC means Avigilon Control Center; Unity refers to Avigilon Unity Video.

Confirm the exact path with Technical Support before rescheduling. Avigilon says it has removed problematic downloads and is blocking affected ACC 7 upgrades to Unity 8.x in Avigilon Software Manager. Its partner communication also directs a pause on the listed paths until an official resolution is released and certified. ## Why a working system still needs attention The technical notice attributes the failure to mismatched secondary indexes in the event-log database. Background retention maintenance can encounter those inconsistencies and crash the service, potentially leaving the server in a continuous crash loop. Cleanup may occur 14 days or longer after an upgrade, depending on retention settings. That describes typical timing, not a grace period or a deadline after which a site is clear. Contact support now rather than waiting for symptoms. The notice limits potential loss to system event logs, license plate recognition (LPR), point-of-sale (POS) and analytics event metadata, plus saved bookmarks and protected videos. The partner email warns that mitigation may require a database reset. Technical Support should assess preservation options and the mitigation plan for each site. ## DSE recommendation and immediate next steps The following operational steps are DSE recommendations based on the vendor guidance: - Hold the work. Flag affected upgrades in maintenance schedules and notify the site owner and service team. Include the broader ACC 7 planning hold above. - Check upgrade history. Record the current build, previous build, upgrade date, and retention configuration. The installed version alone does not show how the site reached it. - Open a support case immediately if already upgraded. This includes affected source versions in the table and the notice’s explicit instruction for recent ACC 7 upgrades to ACC 7.14.46.4 or Unity 8.8.0 or later. If history is uncertain, ask support to assess it. Provide the version history and any observed errors. - Follow support-directed mitigation. Have support guide monitoring, data preservation, and recovery. Do not independently reset the database or roll back the system based on this article. - Verify before resuming. Obtain the vendor’s official resolution and confirmation of the supported upgrade path before scheduling the change. ## Verification and evidence Keep the support case, responsible owner, version history, and vendor instructions in the change record. After support-directed work, document the requested checks for server stability, footage retrieval, event metadata, bookmarks, and protected videos. Record remaining limitations before closing the case. The partner communication says a support tool and resolution are being developed and that end-user emails are planned for September 15, 2026. It does not provide a release date. Recheck the notice with support before acting. ## Official references and support - [Motorola Solutions MTN-0168-26](https://docs.avigilon.com/bundle/global-mtn-0168-26/) — issued September 2, 2026; [direct PDF](https://docs-be.avigilon.com/bundle/global-mtn-0168-26/raw/resource/enus/global-mtn-0168-26.pdf). - Avigilon partner communication — upgrade pause and planned September 15 customer notification. - [Avigilon Technical Support](https://www.avigilon.com/support/help) · [Open a support case](https://support.avigilon.com/s/contactsupport). - DSE customers can also [contact the DSE helpdesk](https://help.dsesecurity.com/) for help coordinating their response.
