Migration options Overview
Option 1:
New installation
You install new system on
SAP HANA
Either without changing existing
solutions (greenfield)
Or for transforming existing
solution to SAP HANA by
performing (selective) data
migration
Option 2:
Classical migration
To bring original system on
release supported by SAP HANA,
you perform update/upgrade
(if required)
Then, you classically migrate
your traditional database to
SAP HANA
Option 3:
One-step upgrade and
migration with DMO
You use database migration
option (DMO) that combines
upgrade and database migration
in one step
One process, one tool, one
downtime

Migration options & tools 1. New installation for transformation
Overview
Address changes to existing solution landscape by transformation with
SAP Landscape Transformation software with reduced effort to build targeted landscape
(such as via shell creation with carve-out options + system consolidation)
Complemented by transformation services (such as Data Management Services
or System Landscape Optimization consulting services)
Benefits
Provides opportunity to correct design issues
– System consolidation
– Harmonize data as part of the migration (chart of account, master data)
Leveraged flexibility by offering selective migration
– Migrate only specific data without business disruption (such as of last two years)
– Combine data cleansing – leave unused master data behind
– Smoothly introduce new business processes (for example, new general ledger)
Minimized downtime service available

Challenges
Increased effort to deploy

Migration options 2. Classical migration: overview
Overview
You perform upgrade (if required) + heterogeneous system copy with classical migration tools
Benefits
Results in nearly identical system
Minimal impact on functional teams
Separation of concerns
Challenges
Typically requires extended downtime (depending on DB size) and several downtime windows (depending
on scope)
With inclusion of upgrade, fallback to original state only possible via restore

Choosing the right option Standard recommendation
General Recommendation
DMO
is the standard procedure for
migrations to SAP HANA –
profit from a simplified
migration to SAP HANA with
minimized overall project costs!
Reasonable Alternative
Classical migration
If DMO does not fit your
requirements, consider to use
classical migration with
software provisioning manager
(continuously improved for this
migration use case)
Possible Exception
New installation for
transformation
In addition, there are further
migration procedures for special
use cases, such as system
consolidation or carve-out with
SLO Shell Creation
Use as starting point for
your individual assessment
