Hello Raghuramireddy vennapusa,

• Using DMO can we able to perform above migration ?
  >>> No.
  DMO with target database DB6 is not supported if the source database is also DB6.
  
  
• with out upgrade DB2 can we able to upgrade EHP8 ?
  >>> No.
  Support for Db2 V9.1 through SAP has ended on 2017-12-31
  
  
• Any possibility to upgrade DB2 to latest and SAP application EHP8 single downtime ?
  >>> No.
  Enhancement Package 8 for SAP ERP 6.0 is based on SAP NetWeaver 7.5.
  
  As described in SAP note#2158828, minimal DB-version has to be applied before the upgrade to NetWeaver 7.5 can take place.
  
  2158828 - Minimal DB system platform requirements for SAP NetWeaver 7.5
  Here, the minimal DB-version is 10.5 FP6SAP.

Note:
You can not directly upgrade the database to Db2 10.5 or 11.1. (note#101809)
Please upgrade to Db2 9.7 first.

Hello Raghuramireddy,

A possible roadmap could be:

• DB upgrade (Db2 9.1 => 9.7 => 10.5 or 11.1)
• Hetero. system copy (AIX => Linux)
• SAP upgrade (EHP 3 => EHP8)

Kind regards

Dear Maria,

i'm clear about my question and your answer but my manager requesting more specific to check with you on below.

• Using DMO can we able to perform above migration ?
  >>> No.
  DMO with target database DB6 is not supported if the source database is also DB6.

[raghu] are you saying the source DB and the target DB must be different for using DMO tool?

[raghu] DMO cannot be used when source and target DB are the same regardless of whether it is DB6, oracle, mssqsl, is my understanding correct?

• with out upgrade DB2 can we able to upgrade EHP8 ?
  >>> No.
  Support for Db2 V9.1 through SAP has ended on 2017-12-31

[raghu] okay.

• Any possibility to upgrade DB2 to latest and SAP application EHP8 single downtime ?
  >>> No.
  Enhancement Package 8 for SAP ERP 6.0 is based on SAP NetWeaver 7.5

[raghu] are you saying that there is no other tool except DMO to automate the migration?

Thank you,

Raghu
