DMO System Move - SUM uses Source Domain Sap Service User in Target Local Installation

[former_member736642]

Dear Experts,

I am currently doing a DMO CUUC with System Move from MSSQL to HANA. SUM was started in target PAS after initial transfer of SUM. SUM was able to detect the new host as the target host and continued with phase HOSTCHANGE_MOVE. It asked for the information on target such as PAS instance number, profile and now checking the HANA db user store using the <DOMAIN>\SAPServiceSID user of source. Target PAS is not added to domain and is a local installation. This check is failing. Is there any file in SUM directory that can be modified so it will use the local SAPService user instead ? Is it necessary for SUM system move that target system PAS also belongs to the same domain as source? SUM used is SUM 1.0 SP26.

If below command is run manually with local SAPServiceSID it works but SUM is using Source SAP service user. There is no option to change the Service user or domain in SUM utilities only the password. Also, based on the Environment dump logs, SUM is able to obtain the environment of target host, and details are correct.

HDBOPUSS.LOG

EXECUTING D:\usr\sap\SID\hdbclient\hdbuserstore.EXE -u <Source Domain>\SAPServiceSID LIST DEFAULT Error 91001: System call 'LookupAccountName' failed, rc=1332:No mapping between account names and security IDs was done. SAPup> Process with PID 2744 terminated with status 1 !

Appreciate any advice. Thanks.

Hi Clarisse,

The different domain for source and target host in "Windows" to "Windows" migration is supported by SUM 2.0 scenarios. There was earlier a problem in Domain name handling if the domain changed in target but that was fixed some time back.

For SUM 1.0, the restrictions in 2882431 are still applicable.

Hello Clarisse,

From the description it appears the target PAS is running on Windows ? If so, I refer you to the note :

2882431 - Database Migration Option (DMO) of SUM 1.0 SP26

The section :
----------------< Update D044220 26/JAN/2021 >--------------------------

c) "DMO with System Move": Requirements and Restrictions

Requirements for Source System and Source Database:
...
...

Requirements for Target System and Target Database:
...

• OS of PAS host: Linux only
  

I think this may be the problem.

Thanks, David. I clarified this with SAP and currently waiting for their response. Originally our target was Linux however, down below of the same SAP oss note 2882431, they added the following restrictions, hence, we placed a temporary staging Windows server just to meet this restriction and plan to move PAS to Linux afterwards.

Restrictions:

With regard to operating systems:

For "DMO with System Move" with SUM 1.0, the OS of the target application server has to be Linux or Windows. Note the following options:

• SAP source systems runs on Windows OS: The target PAS host must run on Windows OS. If possible, (that is, if it is supported according to PAM), you can consider the previously mentioned workaround where you install in the source system an AAS running on Linux OS to enable the move to a target PAS host on Linux.
