Migration to Cisco PDSN

Migration Steps

Migration to the Cisco PDSN Release 5.2 image is more than replacing Multi-processor WAN

Application Module (MWAM) cards with SAMI modules. Ensure that you plan your migration such that

migration activities have a minimal impact on an existing mobile subscriber’s service connections.

Table 3 lists the migration tasks that are based on the scenarios established in Table 2.

Table 3 Migration Steps from Cisco PDSN 4.0 to 5.2

Scenario Migration Steps

• In SAMI cards with the Cisco PDSN Release 4.0 image, erase configuration on all

processors and reload Cisco PDSN.

• Configure the I/O memory (IOMEM) on all processors as 256 MB and save the

configuration to the NVRAM.

Note If you have set the IOMEM size as 64 MB, ensure that you configure the memory

lite command. The recommended memory size is, however, 256 MB.

• Upgrade to Cisco PDSN Release 5.2 and reconfigure the Cisco PDSN configuration on

processor 3.

• Provision MS and PCFs to use the newly added Cisco PDSN Release 5.2-based PDSN

IP.

• Provision the newly added PDSN with the HA to service MIP calls.

To minimize provisioning tasks, Cisco PDSN Release 5.2 reuses the IP address and routing

scheme used in one of the Cisco PDSN Release 4.0 processors.

1. MS = Mobile Station.

2. PCF = Packet Control Function.
