Migration Overview
In order to migrate to Release 9.8 of the Cisco PGW 2200 Softswitch software, you need to install the
software on both the active and standby Cisco PGW 2200 Softswitch hosts.
During the migration procedure, you must set each host to both active and standby. For clarity, the
Cisco PGW 2200 Softswitches are labeled PGW 1 and PGW 2. PGW host 1 is the host that is active at
the beginning of the procedure, and PGW host 2 is the host that is set to standby at the beginning of the
procedure.

Cisco PGW 2200 Softswitch supports both Sparc-based and Opteron-based platforms on Release 9.7(3).
Prior to Release 9.7(3), only Sparc-based platforms are supported. In order to migrate to Release 9.8(1),
you need find out the old Cisco PGW 2200 Softswitch software version, the old Sun platform, and the
target Sun platform you are going to use.
See the Cisco PGW 2200 Softswitch Hardware Installation Guide (Release 7 & 9) to find out supported
Sun platforms for Cisco PGW 2200 Softswitch software Release 9.8.
Table 5-2 shows migration procedures to Cisco PGW 2200 Softswitch Release 9.8 across different
platforms. The target platforms are listed in the first column. You can find the migration procedure based
on your target platform and your existing Cisco PGW 2200 Softswitch platform.
