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 process is similar for all CHARON-AXP models.

Creating CHARON Virtual Machine

...

Specify the HP Alpha model to be emulated and the name of the VM then press the "Create" button:

The VM will be created:

Select the VM from the left pane and switch to the "VM Configuration" tab.

In order to reproduce the target HP Alpha configuration, press the "Edit Configuration file" button:

Installation of HP Alpha operating system

...

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

P00>>>boot dqa0

Install HP Alpha/VMS including DECnet on "dka400". The DECnet address must belong to the same area as the source HP Alpha system.

Making remote backups

Now we are ready to create the disk backups of the source HP Alpha system on the CHARON VM.

...

When the backup operation will be completed, the disk "DKA300" of the CHARON VM will contain 3 savesets: "DKA0.BCK", "DKA100.BCK" and "DKA200.BCK".

Restore backups to CHARON-AXP disks

...

The NIC can be disabled with a interface="(disabled)" statement in the CHARON VM configuration file.

Alternative ways of data transfer

...

Connect a SCSI tape drive to the CHARON-AXP host via a PCI card
- Map the tape drive in the CHARON VM configuration file
  a. Restore the source HP Alpha system backups from tape to disk images via OpenVMS running on the CHARON VM.
  b. Boot from standalone backups and restore the content to the CHARON VM virtual disks
- Dump the source HP Alpha system backups to tape images using the "mtd" utility and:
  a. Boot from the freshly installed OpenVMS system and restore the tape images to the CHARON VM virtual disks
  b. Boot from the standalone backup and restore the content to the CHARON VM virtual disks
Create a network cluster between the source HP Alpha system and the CHARON VM (it is possible to use the source system as a boot server); then perform simple backups from one disk to another:
$ BACKUP/IMAGE/IGNORE=INTERLOCK REAL$DKA0: DKA0:
