Oracle Linux 6.10 – Changing the Oracle user's ID & GID

All we need is an easy explanation of the problem, so here it is.

OS: Oracle Linux 6.10

DB vers: 12cR1

I will backup and restore from NFS shared disk for a preprod server. However, the ID and GID of the oracle user on the production server (shared disk on producution) are different from the preprod server. For this reason, I need to change the ID and GID information, otherwise I cannot see the backup files on the preprod server. However, when I do this, there will be a problem on the datafile, oracle home and other existing ownerships on the preprod server. How can I perform this operation with the least amount of problems? It’s fine as long as the downtime isn’t taking too long on the preprod server.
