Product data

Chapter 12. High availability and redundancy 323
The Director data is at a Snapshot level that is equivalent to when you started the
upgrade. Events received during the upgrade will be lost.
Note: You should not deviate from the above procedure, or you might reload
both nodes. Currently, upgrading mirrored data imposes restrictions on when
you activate the new code (although this may be changed in future releases).
Note: A snapshot of each node should be taken prior to upgrading the SDMC
nodes so that they can be restored should problems arise during the upgrade
process.
