Environment
- App Control Server: 8.10.2
Symptoms
During server upgrade the step Executing 'migrate'. Please wait... seems stuck, but the time elapsed continues to count up.
Cause
A table restructure during the upgrade process must complete, and depending on the number of antibody instances and the SQL resources available this process could take many hours to complete.
EP-19460: Changed how we store yara tags associated with file instances to improve query performance and to significantly reduce disk storage usage.
Resolution
Customers upgrading to Server 8.10.2 may experience longer than usual upgrade times due to important changes made to improve the performance and reliability regarding the storage of Yara rule tags.
Customer installations with a high volume of Yara tags associated with files are most likely to experience these longer wait times.
Additional Notes
- The What's Currently Running script could 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 in excess of 4 hours.
