Upgrading a Call Server from CP PII to CP PIV
In a Campus configuration, as both cores may be
physically separate, it is important to plan for required
attendance at both core sites at some point in the
upgrade.
Preparing for an upgrade involves the following tasks:
• Identify and become familiar with all procedures.
• Verify that all installed applications meet the minimum software
requirements for the target platform.
• Determine and note current patch or Dep lists installed at the source
platform.
• Determine required patch or Dep lists at the target platform for all
system-patchable components (Call Server, Voice Gateway Media
Cards, Signaling Servers and so on).
• Determine the required patches or DEP lists installed on all applications
(CallPilot, Symposium Call Center Server, and so on).
• Determine and communicate the required maintenance window,
contingency plan and the impact to the customer to complete the
procedure.
• Perform an inventory on required software and hardware.
• Secure the source software and key code.
• Secure the target software and key code.
• Verify the new key code using the DKA program.
• Print site data.
