Migrating 18c from Oracle Linux 6 to 7

chrisseonMay 24 2020 — edited May 30 2020

Hi,

Our 18c databases are currently on NetApp and HPE and we are planning to migrate the databases from the existing server running Oracle Linux 6 to a new server running Oracle Linux 7. Would it be possible to simply unmount the data file directories on Linux 6 and mount it to the new server running Linux 7? If that is not possible due to the differing OS versions, what would be the fastest way to migrate the data over to the new OS? Trying to avoid data dump.

Thanks.

What specifically did you change in your Network Gateway?

Only the IP Address changed from A.B.C.D to A.B.C.E

That's what I thought. In your question mentioned that no IP was changed. 

Recently we had to change the network gateway for our 2 node MySQL cluster running on top of Oracle Grid (RHEL). None of the IPs changed. We noted the following behavior:

Can you look in the location below and make sure that the file reflects your changed IP. 

/etc/hosts

The gateway IP address is not in the  hosts file, it is (and has only ever been) in a routing table.

1 - 4
