Upgrade process on DR server
We have DR set up for our ECC production system. we want toupgrade from 4.6c to ECC 6.0. Could you please explain the process for this upgrade?
Specific question here is do we need to upgrade SAP and DB on both primary and DR site?
I recommend the steps, below;
1) Stop DR site before the upgrade
2) Perform the upgrade process at the primary site
3) At the end of the upgrade, take a backup of your new system and restore to the standby
4) Apply the offline redolog gaps, open DR site and start the log shipment.
Don't forget to copy new kernel to the standby site
