Hello Experts,

Now i need to migrated the CI (abap+java) from the old hardware to a new hardware.

Thanks & Regards,

When it comes to Java, you must always follow the SAP System Copy guides.

In short:

You have to run an special Java-export on the source server with sapinst

and then perform a new installation on the target server with sapinst.

When it comes to java, with the result from the export as input.

Please note that you have to be really careful and test this in an test environment first. This is due to the fact that you are keeping the db-server

and "only" installing the central instance again.

- Go to [NW04 installation|http://service.sap.com/nw04installation]

- SAP Web AS

- SAP Web As 6.40 SR1 and Related Documentation

- Homogeneous and Heterogeneous System Copy

Here you have system copy guides for both ABAP and Java.

in the target system you have to install an distributed installation and only install the ABAP-part with the java add-in.

And again, test it first since this could affect your database.

Hi Vera,

What OS do you use? if it is Unix, then the easiest way is copy everything (/usr/sap, /sapmnt DB etc)

from old to new server, then change the hostname and IP of the new server to the old name, and here you go.
