Export completed successfully.
Once the export is complete we are done with source system and source system SAP application
can be started.
To move the backup /PD1_export to the target.
Various options available.
We will use the mount option.
To mount the backup location below are steps.
Login to putty on PD1 server as root which is PD1IX100 – 10.0.1.19.
Type yast
The following screen will appear.

Login to Target – UD1 – UD1IX100 – 10.0.1.11
Login as root
Create an empty folder under “/” with same name (PD1_export)
Mount the /PD1_export from source to target.
Go to /PD1_export folder on the target and validate the content.
Make sure SAP system is available on target If there is an SAP application uninstall the sap
application using sapinst.
After the uninstall (CI & DB) are deleted and oracle software & client software are intact.
Now you can run sapinst and start the installation on target.
From the below location on UD1IX100 start the sapinst as root.

Usually if its an ABAP+JAVA system it takes long time to start the java processes so sapinst errors
out.
To fix the error.
Stop the sapisnt for now and restart SAP manually and re-run sapinst.
When the SAP application is stopped
Start SAP application. (startsap all)
Now re-run sapinst again
Login as root and go to the media location for sapinst.
