:!: Note: DMO is not a tool, it is one of several use cases for SUM.
Note: You may consider to enable the table comparison in a productive run as well i.e. for certain tables only, if it is required to prove that the content is identical.
For more information on this topic, see Migration of SAP Systems to SAP HANA.
:!: Note: the migtools are not really tools, but use cases for SUM.
:!: Note: For classical migrations using the Software Provisioning Manager, there are also migration tools (such as Migration Monitor, splitter tools – and Table Checker, as mentioned above), which you must not confuse with the migtools of SUM with. For more information about the migration tools of the classical migration, see SAP Note 784118.
Aspect | table comparison of DMO | table comparison standalone |
---|---|---|
Use case | Table comparison during migration run using DMO of SUM; the dialog "Database Migration Option" offers to enable and configure the table comparison | Table comparison during classical migration run using SWPM: SUM has to be started separately as migtool |
Focus | Same for both: Tables for which the content shall be compared: either you list specific tables, or a percentage of all tables | |
Integration | Yes: option is part of DMO | No: not part of DMO; manually execution required for use in classical migration |
Drill down possible | Yes: if difference appears, drill down is done to identify the row with different content | No: only tables are listed that show a difference |
Documentation | Part of DMO guide (section 7.2) | Part of System copy guide (section Table Comparison with Software Update Manager) |
Note: there may be scenarios for which only the "old" table checker tool (described in SAP note 2009651) can be used, e.g. access to source database is no longer possible to generate CRC files with SUM table, but the export files with TOC are still available.
