The VM that is being upgraded is referred to as the standby system and the VM that is managing the additional traffic is referred to as the active system. All the examples in this document assume a Linux/Unix environment. Alternatively, utilities such as psftp.exe and putty.exe can be used in a Windows environment to SSH. The screen captures for the system pre-upgrade, upgrade, and rollback between releases are the same with the exception of the version numbers in these screen captures. |
It is recommended that you upgrade the software when the traffic levels are low to avoid the risk of triggering network congestion on the active system.
If you have to reset the system date and time, it is recommended that you perform this task during the maintenance window. For more information, refer to the DSC - SP2000 Platform Manager User Guide.
