旧版本：
HANA1.2 SP12单租户
目标版本:
HANA2.0 SP02多租户
一． 操作步骤
- 下载SAP HANA 2.0软件
- 检查硬件和操作系统要求
- 备份数据库
- 解压HANA2.0然后运行hdblcm
选1
重新运行hdblcm，选1
finally：
二．选择HANA 1.0还是2.0
You should use it when you…:
2. want to benefit from new performance features like Dynamic result Cache, improved garbage collection / locking, optimized compression, HEX (HANA Execution Engine)
3. want to use event triggered a log backups
4. want to install license keys for individual tenant databases
5. want to use Data Shipping Parallelization within HSR
6. want to use redo log encryption (1642148)
7. want to restore a single database backup directly into a tenant database (2096000)
8. want to lower your TCO with persistent memory (pmem) / NVM / NVRAM (2618154)
You have to use it when…:
9. it is planned to use S/4 HANA 1709 (2524661)
10. it is planned to use HSR active / active (2391079)
11. it is planned to use POWERPC SLES12 LE (little endianness)
12. you want to use special functions/features in SDA / SDI / SDQ (more supported remote databases and functions/syntax)
13. you want to migrate from INTEL to PowerPC or vice versa via restore/recovery (1642148)
14. you want use Cross-SID-copy: Backint-based backups of a tenant database ca be recovered into a tenant database using a target SID or tenant NAME that is different to the original one (2096000)
15. you want to use HANA Cockpit 2.0 (running only on HANA 2.0)
16. it is planned to use secondary time travel feature with HSR (HANA 2.0 SPS03)
17. it is planned to use multi-target replication (HANA 2.0 SPS03)
You should not use it when…:
18. you are currently on old hardware: Haswell and older => recommended to buy new HW (2399995)
19. you are using SLES11 SP4 BE (big endianness) with PowerPC and don’t want to migrate (till end of maintenance of SLES11 SP4)
20. currently no feature used and not planned to use which only comes with HANA 2.0
21. you want to avoid using MDC (default mode since HANA 2.0 SP01)
22. you are using XSC (XS Classic) and not ready to use XSA (XS Advanced) – XSC is still supported but not recommended (2396214)
23. you are using a deprecated feature (2425002)
24. your current release / product is not supported on HANA 2.0
25. you are affected by the limitation using cross tenant access (2196359 / 2312583)
翻译几个看得懂的就是：
选择2.0理由：
26. 希望针对单租户数据库使用License keys
27. 希望使用带HSR (HANA System Replication) 的数据传输平行化
28. 计划使用S/4HANA 1709（Note 2524661）
29. 希望通过恢复（restore/recovery）的方式，从Intel转换到PowerPC，或者相反
30. 希望使用Cross-SID-copy：一个租户数据库的Backint-based备份，可以恢复到使用不同目标SID或者租户名称的另一个租户数据中。
31. 希望使用HANA Cockpit 2.0（仅支持HANA 2.0）
选择1.0理由：
32. 希望避免使用MDC（从HANA 2.0 SP01开始成为默认模式）
33. 正在使用HANA 2.0中已经弃用的特性（Note 2425002）
34. 当前使用的版本/产品不支持HANA 2.0
