Hello Bala,

I recommend you the following steps :

-> Create the complete liveCache backup & APO database backup before to start the migration procedure.

-> Run the migration steps using the recommended document & note from the above reply.

-> If there are any problems => you could create the SAP message and get the support from SAP via OSS, you are SAP customer.

-> And you could restore your system, if you failed with the migration steps, using the SAP notes::

457425 Homogenous liveCache copy using backup/restore

210564 Copying a complete APO system

< using the complete liveCache backup & APO database backup created before migration >

Thank you and best regards, Natalia Khlopina

Check note 886103 - System Landscape Copy for SAP SCM and the section "APO Heterogeneous System Copy:" how to backup your livecache content to the APO database and restore it to a new server.

The problem you will face is that livecache 7.4 is no more available for your target platform since it´s out of support. Do you have an extended maintenance contract?

Check note 57425 - Homogenous liveCache copy using backup/restore

how to do it technically.

For your release: APO 3.1 + livecache 7.4 is out of maintenance since end of 2006. I highly suggest upgrading to a higher release.
