15.2.4  Other migration applications
There are a number of applications available from other vendors that can assist in data 
migration. We don’t discuss them here in detail. Some examples include:
򐂰
Softek Data Replicator for Open 
򐂰
NSI Double-Take
򐂰
XoSoft WANSync
There also are storage virtualization products which can be used for data migration in a 
similar manner to the Piper tool. They are installed on a server which forms a virtualization 
engine that resides in the data path. Examples are:
򐂰
IBM SAN Volume Controller
򐂰
Falconstore IPStore
򐂰
Datacore SANSymphony
An important question to ask, before deciding among these methods, is whether the 
virtualization engine can be removed from the data path after the migration has completed.
15.3  IBM migration services
This is the easiest way to migrate data, because IBM will assist you throughout the complete 
migration process. In several countries IBM offers a migration service. Check with your IBM 
sales representative about migration services for your specific environment and needs.
Businesses today require efficient and accurate data migration. IBM provides technical 
specialists at your location to plan and migrate your data to your DS6000 disk system.
This migration is accomplished using either native operating system mirroring, remote 
mirroring, or the Piper migration tool to replicate your data to the DS6000 disk system with 
minimum interruption to service. In addition, IBM will provide a Migration Control Book which 
specifies the activities performed during these services.
The benefits of IBM migration services include:
򐂰
Minimized downtime and no data loss.
򐂰
Superior data protection that preserves data updates throughout the migration, allowing 
the process to be interrupted if needed.
򐂰
Migration Control Book
 that details the work performed, so your staff can use it for post 
migration management.
15.4  Summary
This chapter shows that there are many ways to accomplish data migration. Thorough 
analysis of the current environment, evaluation of the requirements and planning are 
necessary. Once you decide on one or more migration methods, refer to the documentation 
of the tools you want to use to define the exact sequence of steps to take.
Special care must be exercised when data is shared between more than one host.
IBM Global Services can assist you in all stages to ensure a successful and smooth 
migration.
