The correct answer is D. HANA database export and import. HANA Database Export and Import (D) is correct because it supports cross-version migrations (HANA 1.0 → 2.0) and cross-OS migrations (SLES 12 → 15) in a single operation.

Question
Your on-premises network contains the following:
- A 1-Gbps internet connection
- An SAP HANA 1.0 instance that has a 4-TB database
- An SAP landscape that uses SUSE Linux Enterprise (SLES) 12
You have an Azure subscription that contains a virtual machine. The virtual machine is of the M64s SKU and runs SLES 15 and HANA 2.0. You need to migrate the database to the virtual machine and upgrade the database to HANA 2.0. The solution must meet the following requirements:
- The migration must be performed during a weekend.
- The database can be offline during the migration.
Which migration method should you use?
Options
- AAzure Data Box
- BHANA database backup and log shipping
- CAzure Migrate
- DHANA database export and import

Explanation
HANA Database Export and Import (D) is correct because it supports cross-version migrations (HANA 1.0 → 2.0) and cross-OS migrations (SLES 12 → 15) in a single operation. The database can be taken fully offline during the weekend window, and a 4-TB dataset is transferable over a 1-Gbps connection within that timeframe (~9-10 hours at sustained speed). This method uses HANA's native tools (hdbdatacopy or the HANA Studio export/import wizard), making it the purpose-built choice for this exact scenario.
Why the others are wrong:
- A. Azure Data Box is a physical device for large offline bulk data transfers to Azure storage - it doesn't understand HANA internals or perform version upgrades; it would take days to ship the device.
- B. HANA backup and log shipping is designed for minimal-downtime or continuous replication scenarios; the log shipping component implies the source database stays online, which is unnecessary here and adds complexity.
- C. Azure Migrate is a general-purpose lift-and-shift tool for VMs and workloads; it doesn't handle HANA version upgrades and wouldn't migrate from HANA 1.0 to 2.0.
Memory tip: Think "Export/Import = cross-version upgrade path." Whenever an exam question combines a version change (1.0 → 2.0), an OS change, an offline window, and a moderate database size, HANA's native export/import is the answer. If they said "minimal downtime," think HSR (HANA System Replication) instead.
