I am migrating from an existing HANA server to a completely new server, after which the existing (old) server will be removed. I'm using the backup/restore method.
My question concerns the System ID (SID) on the new server. Because of established procedures, I'd like this to be the same as on the existing server, but the migration guide states that the SID must be unique. Both the existing and the new server are single-database and single-system. I can arrange the data movement so that the two systems are not active or online simultaneously.
What are the implications of using the same SID for the old and the new system?
Thanks,
Donn
