Migration Approaches for SAP®
Environments
Homogenous Migration (Lift & Shift or System Copy)
 Both operating system and database are the same in Source and
Target System
 Standard SAP® System Copy process can be used
 Tool based migration performed with block level copy processes
Heterogeneous System Migration
 At least one of the following is changed during the copy:
• Operating system
• Database system
 SAP® Certified Migration Process
Rebuild
 Rebuild/Clone of Common Usage Pattern (App Server, SAP®
Engines)
 Limited Transactional Data

SAP® Migration Approaches
for Heterogeneous System
Migrations Need to Stay
Within the Guardrails…
• Migration approach must follow the SAP
approved Heterogenous Migration
Process
• Size move groups appropriately for both
the number of applications as well as the
amount of data
• Size move groups to fit within the
approved migration window
• Test system interdependencies and
interfaces early in the process
• Risk mitigation through mock runs of
production
in the target production environment
• Consistency of approach for each
application across Dev, QA, and Prod

Don’t fall into these
traps…
• Networking is one of the primary reasons for delays in the
project:
– DNS Settings incorrect
– Hardcoded hosts files with IP addresses on the servers
or on the desktop
– Subnet conflicts between source and cloud because of
improper documentation
• Unexpected configuration not clearly defined upfront:
– Multiple uses for a single database (HANA)
– Multiple uses of a single server (Homogeneous
migrations)
• Clearly define who is doing 3rd party application
migrations/installations
• Should be like for like testing, not addressing new
enhancements. Be careful not to introduce change during
the migration.

Disaster Recovery Options
Replication Model
 Data replicated from primary to secondary site for database
systems
 Recovery Point Objective: 1 hr
• Available to recover data from point 1 hr before disaster
 Recovery Time Objective: 4 hrs
• Secondary site will be up and running in 4 hrs
 More Costly but quicker disaster recovery time with lower
data loss
Backup Model
 Data backup taken from primary site every 24 hrs and
moved to secondary site
 Recovery Point Objective: 24 hrs
• Available to recover data from point 24 hrs before
disaster
 Recovery Time Objective: 24 hrs
• Secondary site will be up and running in 24 hrs
 Lower cost but higher turnaround time and higher data loss
