Overview
Data migration is a one-time movement of data from a source to a target. Typical
examples are data center refreshes where data is moved off an old array after which
the array is retired or re-purposed. Data migration is
not
data movement due to
replication (where the source data is accessible after the target is created) or data
mobility (where the target is continually updated).
After a data migration operation, applications that access the data must reference the
data at the new location.
To plan a data migration, consider the potential impact on your business, including:
l
Type of data to be migrated
l
Site location(s)
l
Number of systems and applications
l
Amount of data to be moved
l
Business needs and schedules
Data migration solutions for open systems environments

environments.
Non-Disruptive Migration overview
Non-Disruptive Migration (NDM) provides a method for migrating data from a source
array to a target array across a metro distance, typically within a data center, without
application host downtime. NDM requires a VMAX array running Enginuity 5876 with
required ePack (source array), and an array running HYPERMAX OS 5977.811.784 or
higher (target array). Consult with Dell EMC for required ePack for source arrays
running Enginuity 5876. In addition, refer to the NDM support matrix available on eLab
Navigator for array operating system version support, host support, and multipathing
support for NDM operations.
If regulatory or business requirements for DR (disaster recovery) dictate the use of
SRDF/S during migration, contact Dell EMC for required ePacks for SRDF/S
configuration.
The NDM operations involved in a typical migration are:
l
Environment setup – Configures source and target array infrastructure for the
migration process.
l
Create – Duplicates the application storage environment from source array to
target array.
l
Cutover – Switches the application data access form the source array to the
target array and duplicates the application data on the source array to the target
array.
l
Commit – Removes application resources from the source array and releases the
resources used for migration. Application permanently runs on the target array.
l
Enviroment remove –Removes the migration infrastructure created by the
environmental setup.
Some key features of NDM are:
