To prevent the issue, follow the best practice which is to upgrade both the Deep Security Manager and Deep Security Relay first, and then upgrade the Deep Security Agent.
It is also recommended to have a higher build version for Deep Security Manager and Deep Security Relay than the Deep Security Agent version. Make sure the version is higher than 10 U14 or 11 U2.
