migration

This chapter includes the following topics:

■ Types of data migration

Types of data migration

This section describes the following types of data migration:

■ Migrating data from LVM to Storage Foundation using offline migration

When you install Storage Foundation, you may already have some volumes

that are controlled by the Logical Volume Manager. You can preserve your

data and convert these volumes to Veritas Volume Manager volumes.

See “About migrating Logical Volume Manager to VxVM” on page 391.

■ Migrating data between platforms using Cross-platform Data Sharing (CDS)

Storage Foundation lets you create disks and volumes so that the data can be

read by systems running different operating systems. CDS disks and volumes

cannot be mounted and accessed from different operating systems at the same

time. The CDS functionality provides an easy way to migrate data between one

system and another system running a different operating system.

See “Overview of CDS” on page 455.

■ Migrating data between arrays

Storage Foundation supports arrays from various vendors. If your storage

needs change, you can move your data between arrays.
