6. Run

automatically reboot.

Software Update Flow
The basic flow of the software update process is illustrated in the diagram below.
The ION Accelerator software starts out in the initial state.
After the
software:upload
command is executed, an
update is present in ION Accelerator’s dropbox (if verification
passes). The patch can be applied with the
software:apply
command, which either completes or fails. If it fails (failed
state in the diagram), the user can issue the
software:revert
command to discard the patch, or issue
the
software:apply
command again, if the issue
preventing the patch from succeeding has been fixed.
If you are using HA mode and want to wipe the existing
configuration on one or more nodes, you must upgrade both
nodes simultaneously. If you upgrade one node at a time,
then one node will propagate the data to the other, and data
won't be wiped out.
