Put affected upgrades on hold. If your site has already upgraded from an affected version, contact Avigilon Technical Support immediately, even if the system appears to be operating normally.
\r\nMotorola 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.
\r\nMTN-0168-26 identifies these upgrade paths. ACC means Avigilon Control Center; Unity refers to Avigilon Unity Video.
\r\n| Current version | Planned upgrade destination | Required action |
|---|---|---|
| ACC 7.14.44.4 | ACC 7.14.46.4 | Pause |
| ACC 7.14.44 or 7.14.46 | Unity 8.x | Pause |
| Unity 8.7.x or 8.8.0.x | Unity 8.8.1.x | Pause |
Broader planning hold: The notice’s corrective actions also direct customers to halt planned upgrades from ACC 7 to ACC 7.14.46.4 or any Unity 8.8.x version until an official service release is available. Confirm the exact path with Technical Support before rescheduling.
\r\nAvigilon 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.
\r\nThe 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.
\r\nCleanup 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.
\r\nThe 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.
\r\nThe following operational steps are DSE recommendations based on the vendor guidance:
\r\nKeep 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.
\r\nThe 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.
