Disk image system copy causes problems

[Former Member]

Hi

Working with a client who chose to copy a PRD SAP ECC 6.0 system to a new box (as DEV) via a disk image copy. They renamed enough of the new SAP system to get it running but they still have problems.

The command CHGR3SHLOC fails when the PRD box tries to create the mount to DEV. Also the source system name show up in the name of the default & instance profiles even when the old profiles are deleted and regenerated.

I was wondering if anyone had a list of things to be changed when using a disk image to create a new SAP system.

Personally I always do a normal install followed by a DB copy to create a DEV system from a PRD system.

Thanks

Thanks Volker

I checked the list and the new system still has some references to the old server. This means we can not release transports via SE01 as we get a "can not connect" message.

I do see that when I run DSPR3SYS the central instance configuration (Instance hostname) still points to the old server even tho

SAPGLOBALHOST, rdisp/mshost, SAPDBHOST etc point to the new host. Can we change the central instance host info or do we need to delete it and re-create it?

I ran WRKENVVAR and that data looks OK.

Thanks

Hi Matt,

I'm sorry, but I never used DSPR3SYS or similar ... you udefinetely do not need to redo the copy, but you need to fix the root cause. As I do not know your issue, I cannot help you ...

I would change the data area in r3sid400, the profiles and the /usr/sap/trans/config/SID ... (except the rest of my document)

In crazy cases delete of the IFS stuff in /usr/sap & /sapmnt should help as well and then use crtr3sys and crtr3inst ...

For more details, I need to check online ...

Hi Matt,

I would fully agree, that "a full i5 copy" is really crazy .... but at least it works in an "ABAP only" environment ...

You should have a look at:

(ok, you have to make a few own ideas on that, as the customer will not have done the RSTLIB etc. but in general, that is what you are looking for)
