Upgrade to Server Version 8.10.2 + Takes Long Time To Complete

Carbon Black App Control (formerly Cb Protection)


During server upgrade the step Executing 'migrate'. Please wait... seems stuck, but the time elapsed continues to count up.


  • App Control Server: 8.10.2


Upgrades coming from 8.10.0 and below to 8.10.2+ requires a table restructure during the upgrade process. This causes a longer than usual upgrade time.

EP-19460: Changed how we store yara tags associated with file instances to improve query performance and to significantly reduce disk storage usage.


This is expected when upgrading to 8.10.2+.  Upgrade time is highly variable and is dependent on the number of antibody instances, the count of yara tags, and the SQL resources.

Additional Information

  • The "What's Running Now" script can be used to monitor the Individual Query changes and overall duration of this step. The Status column showing "Suspended" is not a cause for concern.
  • Delaying the upgrade will potentially increase the time it takes to complete due to additional Yara tag and file associations.
  • Some customers have reported upgrade times ranging from 1 hour to as extreme as 30 hours.
