The Address Manager hard disk partition layout is modified to support the dual boot feature.
The re-partitioning operation takes a noticeable amount of time, because it must maintain the existing software release while changes are made to the hard disk. After it starts, the entire upgrade process is autonomous and does not rely on any off-platform resources or services. From Address Manager 8.2.0 or greater, Address Manager will run a system check to verify the state of database replication and database size as well as the size of available partitions during any subsequent upgrade operations.
It is critical that the upgrade process completes without interruption; otherwise the appliance may be left in a non-bootable state. A power interruption while disk partitioning is in progress will disable the platform.
