the upgrade process. The deployment of a temporary HDS/Distributor AW may not be necessary
depending on the contact center hours of operation, the estimated upgrade time for each
ICM/IPCC node (for additional information refer to 
), whether one or two HDS/Distributor AWs are deployed,
the reporting user capacity required during upgrade, and other operational factors. The temporary
HDS/Distributor AW does not provide historical reporting, only real-time reporting is provided.
Both examples assume Side A is upgraded first, although the B side can be upgraded first.
Technology Refresh Example 1: Production HDS/Distributor AW Upgraded in Parallel with the Central Controller
In the first example, the production HDS/Distributor AW is upgraded in parallel with the central
controller. If necessary, an ICM/IPCC 7.0(0) temporary HDS/Distributor AW is configured
prior to central controller upgrade maintenance window to enable real-time reporting and
configuration during the time that the production HDS/Distributor AW is off-line being upgraded.
Warning: In order to complete an upgrade successfully, the order of upgrade as defined
in this guide MUST be followed.
Warning: When upgrading a hosted system with multiple instances, you must upgrade
the instances in sequential order (as created).
