Hello Mert,
Indeed, in the HANA Administration Guide, the following is stated:
"A SAP HANA database cannot be recovered to an SAP HANA database with a lower software version. The SAP HANA software version used for the recovery must always be the same version or higher than the SAP HANA database used to create the data backup or storage snapshot."
It's not that dangerous a statement imho, since the backup you're restoring will consist of all data in the database (all deployed HANA content, all data of a SAP installation in the SAPABAP1 (default) schema, database users and their schema's, roles, etc.).
The potential problem you sugest is related to the database content, which you are completely replacing with the content from the backup. You will have the revision 93 database content running on HANA with 112 binaries. I don't see a problem with that right away. You might get issues when you subsequently want to update this 112 to another revision, as then you'll get the post processing for the new revision on your restored data. I have no field experience with this last scenatrio, but have performed a restore to a higer revision without problems.
Kindest regards, Wilbert
