It is mentioned to me that restoring an older revision of HANA backup on newer revision of HANA is okay as far as the Backup and Recovery guide goes. In our case the restore is being attempted from rev 93 to 112. I have not seen this statement myself but it was quoted and seems rather odd why this dangerous statement would be part of the official guide.
Knowing that HANA has different schemas and settings between two revisions, how would it be suggested to restore on higher version, I don't quite understand? I can clearly see some base schemas and certain privileges get wiped out if you do such restore after my clean install of 92 and restoring a backup of on clean install of 112. What are your thoughts?
Is there a safe way to do such restore while copying all data, schemas and additional user/roles/pther catalog objects implemented on top of the base installation to the higher version of HANA? The main objective here is to replicate whatever was configured and populated already on one instance, to another one without having to upgrade the source instance to prevent disruption to the source use and simply switch over to the new one once the testing is completed with the new version.
PS: The other alternative of course I am trying is the install a fresh copy of 93 on another instance, restore the backup on it then upgrade that to 112 which has its own issues too which I am checking on another thread.
Thanks for your input.
