Cisco Cisco Unified Contact Center Enterprise 9.0(1) Guia Da Instalação

Unified ICM/Contact Center 9.0(1) upgrade time and
space requirements

Introduction

Successful upgrade planning requires an understanding of the time and space requirements
necessary to upgrade the various Unified ICM/Contact Center components. The Logger and
HDS upgrades take longer to upgrade than other Unified ICM Contact Center nodes due to the
time it takes to upgrade the HDS and Logger databases.

For technology refresh upgrades, the network configuration between the source and target
hardware also effects the overall upgrade times.

A number of factors affect the database migration time:

The most critical parameters include the following:

•

the overall database size

•

the database profile

•

the type of upgrade (Common Ground vs. Technology Refresh)

•

The upgrade from Unified ICM/Contact Center 8.0(x) or 8.5(x) to Unified ICM/Contact
Center 9.0(1) .If PGs are on their own machine without other components, upgrade is allowed
from 8.0(x) to 9.0(1).

•

the hardware involved, especially the efficiency of the disk subsystem
