 Overview of the Migration
--------------------------
+a-------------------------
 
 The migration process has three major phases:
 
 1. **Preparing your LOCKSS 2.x machine.**
 
    If you are installing LOCKSS 2.x on a new machine (recommended), you will need to commission a new Linux host.
 
-   If you are installing LOCKSS 2.x on a LOCKSS 1.x machine, you will need to perform preparatory actions, which may include (where applicable) upgrading the operating system, or moving LOCKSS 1.x data around between disk volumes.
+   If you are installing LOCKSS 2.x on a LOCKSS 1.x machine, you will need to ensure that the machine meets the requirements for LOCKSS 2.x, and if necessary to upgrade the operating system.
 
 2. **Installing and configuring LOCKSS 2.0-beta1.**
