5.1.6 Is Upgrading Right for Your System?
An upgrade path from previous HP XC System Software releases to Version 3.1 is provided, but HP
recommends a new installation of Version 3.1. This recommendation is consistent with other Linux vendors,
who also recommend a new installation rather than an upgrade because the Linux upgrade operation has
a lower probability of success and does not provide a consistent experience. In some cases, some Linux
RPMs might fail to operate properly after the upgrade.
An upgraded system is similar but not identical to a freshly installed Version 3.1 HP XC system.
Compatibility RPMs are missing on upgraded systems (*.i386 versions), and a portion of the RPMs from
the previous release remain on an upgraded system.
