Scenario:You want to migrate y our existing SAP ABAP sy stem to the SAP HANA databaseYour SAP release needs to be upgraded prior to migration

Use the database migration option (DMO) of the Software Update Manager (SUM):it combines SAP upgrade and database migration to SAP HANA in one tool!Benef its:

Migration steps are simplif iedSy stem update, Unicode Conv ersion, and database migration are combined in one toolBusiness downtime is reducedThe source database remains consistent, so a f ast f allback is possible

MotivationIf y ou want to migrate an existing SAP sy stem (running on anyDB) to a SAP HANA database, required steps maybe a dual-stack split, a unicode conv ersion, a database upgrade of anyDB, an upgrade of y our SAP sof tware, anda database migration to SAP HANA. The Sof tware Update Manager (SUM) includes an option that combines theupgrade with the database migration "database migration option" (DMO) f or SUM. It is sometimes ref erred to asthe one-step migration procedure, compared to the classical migration (i.e. heterogenous sy stem copy, usingSof tware Prov isioning Manager).The DMO is an inplace-migration (instead of a new installation): it upgrades and migrates the existing sy stem whilekeeping the sy stem-ID, host name, and connectiv ity settings stable.

DMO for SAP NetWeaver BW and for SAP Business Suite systemsDMO is av ailable with Sof tware Update Manager 1.0 SP09, and can be used f or sy stems based on AS ABAP. Itcan be used f or SAP NetWeav er BW sy stems f rom 7.0 SP17 (and higher) to migrate to 7.31 (and higher). And itcan be used f or sy stems part of the SAP Business Suite 7.0 (and higher) to migrate to a lev el corresponding toSAP BASIS 7.40 (f or example "SAP enhancement package 7 f or SAP ERP 6.0").DMO processing overviewThe processing sequence is based on the shadow sy stem f unctionality of SUM: the SUM creates the shadowrepository on the traditional database until downtime phase, while in parallel the SAP HANA database is setup(client, schema, ...). Then the shadow repository is copied to SAP HANA, the database connection of the SAPsy stem is switched to SAP HANA database, and then the downtime starts. Af ter migration of the application data(including data conv ersion), the upgrade is f inalized and the SAP sy stem runs on SAP HANA. The traditionaldatabase continues to run and it is not modif ied at all, so it remains a f allback throughout the complete process.DMO is using SAPUI5

Althought DMO is based on the "standard" SUM, a new user interf ace (UI) is used - but only f or the DMOprocedure. The UI is based on SAPUI5, so it's running in a browser, and of f ers some comf ortable f eatures likechecking the log f iles without hav ing to log on to the OS of the application serv er.The new UI is currently only av ailable f or the DMO procedure, but in the long run, it may become av ailable f orother use cases as well.

Please note that for a SAP Business Suite system based on SAP NetWeaver 7.40 (i.e. systems part ofSAP Business Suite 7 Innovations 2013), your SAP NetWeaver Hubs must be on 7.30 or higher. Fordetails, see hp://wiki.scn.sap.com/wiki/display/SLGB/Strategy+beyond+SAP+Business+Suite+7+Innovaons+2011

Boris Rubarth Apr 3, 2014 5:54 PM (in response to Walter Castagno)Hi Walter,not sure if I understand y our scenario ...

Boris Rubarth May 14, 2014 11:05 AM (in response to Walter Castagno)Hi Walter,indeed nZDM in SUM is not av ailable f or the DMO procedure, that is why y ou hav e seenthe inf ormation on the screen: something like "nZDM not supported".

Please note that we distinguish between nZDM (near Zero Downtime Maintenance) whichis an option f or SUM and nZDT (near Zero Downtime) which is a serv ice of f ering (seeSCN document).The slide in ITM212 explained the nZDT approach, which may be combined with DMO,but this does not mean that "with nZDT, nZDM in SUM is used f or DMO".For DMO, we hope to of f er a similar approach like nZDM f or SUM in the f uture - staytuned.Best regards, Boris

Background: the nZDM option is only v isible when choosing the preconf igurationmode "Adv anced", see blog Settings to activ ate downtime minimizationcapabilities in SUM - but f or DMO, the option is not of f ered, so when choosingmode Adv anced, a text is display ed to explain that nZDM not supported with DMO

Luis M Carranza Nov 5, 2014 1:22 AMWe perf ormed an Upgrade and HANA Migration of our BW sy stem f rom BW 7.3SPS 8 to BW 7.4 SPS7 using the SUM/DMO Option.

I just realized that the Activ ation Queue tables of ALL DSOs/BI?/A40 exist in the HANA Database but does not exist in theABAP Data Dictionary.Well actually it looks like they exist in the ABAP Dictionary but If I am going to SE11 and try todisplay one of those tables (or f rom RSA1 try ing to display the Activ ation Queue table f or aDSO) I get the message that table does not exist. It looks like there is not entry in the tableDDTYPES f or this table and that is why SE11 reports that the table does not exist.

Is this normal?The DSO loads and activ ation process are running OK but I am justwondering about this situation.
