number of reporting users. The examples therefore include the deployment of a temporary
HDS/Distributor AW to maintain maximum system functionality and reporting capacity during
the upgrade process.
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).
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
•
whether one or two HDS/Distributor AWs are deployed
•
the reporting user capacity required during upgrade
•
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.
In the first example, the production HDS/Distributor AW is upgraded in parallel with the Central
Controller. If necessary, a release 7.0 temporary HDS/Distributor AW is configured prior to
the 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.

Controller Upgrade Maintenance Window:
