ECC6.0 System Copy from 32-Bit to 64-Bit

[Former Member]

Hi,

We have a hardware migration project for ECC6.0 production system from windows 2003 32-bit to windows 2003 64-bit .

Here is the systems environments

Production System (Source System)

Component Version

Hardware 32-bit Intel Xeon (x86)

Operating System 32-bit Windows 2003 R2 SP2

Database Oracle 10.2.0.2.0 32-bit

SAP Kernel 700 32-bit PL 133

Software Component Release Level Highest Support Package

SAP_BASIS 700 0011 SAPKB70011

SAP_ABA 700 0011 SAPKA70011

SAP_BW 700 0012 SAPKW70012

SAP_AP 700 0008 SAPKNA7008

SAP_HR 600 0015 SAPKE60015

SAP_APPL 600 0008 SAPKH60008

Target System

Component Version

Hardware 64-bit Intel Xeon (x64)

Operating System 64-bit Windows 2003 R2 SP2

Database Oracle 10.2.0.2.0 64-bit

SAP Kernel 700 64-bit PL 133

We can do this task using Homogeneous system copy.My question is:

1) The current package Level of source system is 0011. do I have to upgrade the Package level in source system first then start the system copy. As per the Basis guy support package level 0011 is incompatible with Microsoft 2008 64-bit.

and we might face lot of issues while applying support packages, so he is recommending to go for Windows 2003 64-bit.

2) Source system component version is : ECC6.0, so it means the Netweaver version is 2004s or 7.0??

Please share your experiences.

Regards.

Hi,

On a separate note If you are staying on Oracle 10.2.0.2.0 I would apply Patch 5 and the latest sap bundle, your present

patch level is full of bugs.

Is your database on a SAN?

if so, this is what I did a few years ago:

1. install new server with Oracle 10g and ECC 6.0.

2. when ready to move, shutdow SAP and DB on source system

3. ask your SAN admin to move disks on the new machine

4. start your DB

5. run a DB script to convert db objects to 64-bit

6. start your SAP system

7. Pray the holy Lord.

This will work easily if both machine names are identical.

the good thing is that downtime is under 15 minutes.

Hi,

Thanks for your expert advice. @ Eric ,yes the database is on SAN but the different hardware.So as suggested i have to install O.S,SAP,oracle then export/import.please let me know the DB script to use to convert the db objects to 64-bit .

Regards.

to convert Oracle onjects from 32-bit to 64-bit:

to convert to 64-bit:

sqlplus / as sysdba

startup upgrade;

@?/rdbms/admin/utlirp.sql

shutdown immediate;

startup

@?/rdbms/admin/utlrp.sql

as for the SAN solution, you can move your SAN LUNs from the old server to the new one. This will save you from the export/import step.

move LUN will take less time than using a full export/import.

Hi Nadeem,

As suggested by Nick you need to go with R3load method of homogenous system copy. Use SAPinst to perform export and import.

Additionally since SAP has stopped support for Oracle 10g you need to upgrade your system to oracle 11g. Oracle 11.2.0.3 is the latest supported version available on SAP site.

Oracle upgrade can also be included in R3load method of homogenous system copy.

Extended support for Oracle 10 is still given - if you pay (see note 1110995)

And...you do not need to UPGRADE Oracle when perfoming db export/import, as the database software needs be installed on the new server as well; thus you can export under Oracle 10 and import under Oracle 11...

Hi deepak,

R3load and SAPINST exp/import method is same or different procedure.???In my case i can accomplish the task using sapinst exp/imp method right??

Regards.

Hi Nadeem,

fyi, export/import with SAPINST call R3Load to perform the loading of table, etc into dump file. To mitigate any possible errors, please update your R3* to latest version.

Known issues and fixes are discussed in SAP notes 1076022, 1152240, 1651862

2) Source system component version is : ECC6.0, so it means the Netweaver version is 2004s or 7.0??

It is 7.0

Export, Import method is best approach for this activity, but I would include Oracle upgrade as well.
