Introduction
This section describes how to migrate your HP Alpha system to CHARON-AXP. We will use a sample HP AlphaServer ES40 system running OpenVMS to demonstrate the migration procedure. The This chapter also contains some instructions for Tru64 UNIX, but it mainly concentrates on how to migrate OpenVMS hosts. The process is similar for all CHARON-AXP models.

Collecting information about the source HP Alpha system
The first step is to determine the exact configuration of your HP Alpha hardware in order to create the CHARON-AXP configuration file.

In case of Tru64 UNIX V5 running on the host system it is recommended to use the following commands to get information on the host configuration:
Please reference to the Tru64 UNIX User's Guide for more details. |

The source HP Alpha peripheral configuration in this example is:
| Controller | Devices on controller | Description |
|---|---|---|
| KZPBA | -DKA0 (RZ28) | SCSI disk/tape controller |
| KGPSA-CA | -DGA0 (RZ24) | FC disk controller |
| OPA0 | System console | |
| -DQA0 | IDE CD-ROM controller | |
| EWA0 | Network interface, MAC address: "F8-D1-11-00-67-E6" |
...

So the collected information about the HP AlphaServer ES40 system is:
| Component | Value |
|---|---|
| System Type | AlphaServer ES40 6/667 |
| Serial Number | SN01234567 |
| Number of CPUs | 4 |
| System memory | 512 Mb |

Creation of CHARON-AXP configuration file
Using the above information, the following configuration can be created:

Making disk images
In our example, possible mappings of the KZPBA SCSI controller include disk and tape images. Tape images have not to be manually created whereas you have to provision disk images, as described below.

Installation of HP Alpha operating system
The next step is to transfer the data from the source HP Alpha system to CHARON-AXP. The easiest way to do this is via backups over the network. For this operation we need a bootable, network-enabled operating system on a CHARON-AXP disk image or physical disk.
...
Create an empty disk image for installation of HP OpenVMS and another one for storing backups from the source HP Alpha system as it is shown in the section above.

Run CHARON-AXP and boot from the CDROM named "dqa0" ("migration.cfg" is the configuration file we use in this example):

Restore backups to CHARON-AXP disks
Next, restore the new savesets to their corresponding virtual disks. Login to CHARON-AXP and issue this sequence of commands to restore all the savesets created in the previous step:

Alternative ways of data transfer
Some alternative methods of data transfer are also possible. For example:
