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.
Migrating data from native LVM volume to a VxVM volume using online migration
You may have some volumes that are controlled by the native Logical Volume Manager. You can migrate your data from these volumes to Veritas Volume Manager volumes, with limited application downtime, and an ability to roll back if necessary.
You can migrate LVM volumes in a standalone environment to VxVM with online migration.
See Online migration from LVM volumes in standalone environment to VxVM volumes.
You can also migrate LVM volumes under a VCS HA cluster environment to VxVM with online migration.
See Online migration from LVM volumes in VCS HA environment to VxVM volumes.
Migrating data from a native file system to a Veritas File System (VxFS) file system using online migration
See About online migration of a native file system to the VxFS file system.
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 the Cross-Platform Data Sharing (CDS) feature.
Migrating data between arrays
Storage Foundation supports arrays from various vendors. If your storage needs change, you can move your data between arrays.
