ICM/IPCC 7.0(0) Upgrade Time and Space
Requirements

Introduction

Successful upgrade planning requires an understanding of the time and space requirements
necessary to upgrade the various ICM/IPCC components. The logger and HDS upgrades take
longer to upgrade than other ICM/IPCC 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 times:

The most critical parameters are:

•

the overall database size

•

the database profile

•

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

•

ICM/IPCC 5.0 to ICM/IPCC 7.0 upgrade vs. ICM/IPCC 6.0 to ICM/IPCC 7.0 upgrade

•

the hardware involved, especially the efficiency of the disk subsystem (see Appendix D)

Specific database tables can consume the majority of the overall data migration times due to
their typical size relative to the other database tables, and the operations which must be performed
on the tables during the upgrade.
