Introduction

This section describes how to migrate your VAX system to CHARON-VAX. We will use a sample MicroVAX 3600 system to demonstrate the migration procedure. The process is similar for all CHARON-VAX models.

...

Collecting information about the source VAX system

The first step is to determine the exact configuration of your VAX hardware in order to create the CHARON-VAX configuration file.

...

The source VAX configuration in this example is:

...

Creation of CHARON-VAX configuration file

Using the above information, the following configuration can be created:

...

Making disk images

In our example, possible mappings of the RQDX3 and TQK50 tapes include physical devices and disk and tape images. Tape images have not to be manually created whereas you have to provision disk images, as described below.

...

Installation of VAX operating system

The next step is to transfer the data from the source VAX system to CHARON-VAX. The easiest way to do it is via backups over the network. For this operation we need a bootable, network-enabled operating system on a CHARON-VAX disk image or physical disk.

...

Making remote backups

Now we are ready to create disk backups from the source VAX system to CHARON-VAX.

...

Restore backups to CHARON-VAX disks

Next, restore the new savesets to their corresponding virtual disks. Login to CHARON-VAX 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:

...
