sap version upgrade using database export/import

[Former Member]

Dear experts,

I have a scenario where I need to upgrade from R/3 4.7 to ECC6 sr2. I would like to use database export/import process. Before moving forward like take your expert opinion.

Source system:

R/3 4.7 EE/(ABAP stack)

OS:WIndows 2003 (32-bit)

D:B:Oracle 10g

Target System:

New hardware installed on Virtual environment(VMware). No change of SID

ECC6 SR2 (ABAP stack)

OS:WINDOWS2008 (64-bit)

D:B: Oracle 10g

Hope it was as easy as that.... but is not.

You can do a HSC to move the system to your new hardware in order to take advantage of the resources, but you cannot upgrade the system in the process.

You can upgrade your DB and do a unicode coversion during the upgrade, Yes.

But the upgrade itself has to be done using the SAP Software Delivery tool.

HI Juan,

Thanks for your reply.

I like your approach to go for hardware upgrade 1st first and then we can go for a DB & SAP upgrade.

I am a bit new in this upgrade area so can you please share the procedure to follow for hardware upgrade.

Hi Rajat,

Take an online backup and restore it into the new hardware. After the respectful restore, aplly online redologs on the new system Then, startup the database.

After that you can upgrade the database and SAP system.

Please keep in mind that, you can take tablespaces to the "backup mode".

SQL> alter database begin backup;

Then, copy files from the old hardware to the new one.. After the file copy, you should execute the statement, below;

SQL> alter database end backup;

>> Please keep in mind that, you can take tablespaces to the "backup mode".

This step can be replaced by online backup operation

You cannot do the migration AND the upgrade in one step. In most cases you should do the migration first and then upgrade on the new platform.

And you should also consider a database upgrade to 11g (this can be combined with the migration).

Cheers Michael

Edit: Hm, maybe i am wrong here, i know it is possible to combine a unicode conversion with the upgrade. Lets see what the others have to say.
