I have RHEL5 server with Oracle Home actual location is SAN, which is mounted on this server.
Now for few Reasons I have one more Server with RHEL 6 64Bit.
I will map those storage LUNS there.
What are the various ways to migrate and what are the advantages/disadvantages ?
Point 1: Take backup from old system and go for new install no new server ?
Point 2: Directly Map LUN and with few changes I can achieve this ?
Can I go for creating control files and copy and backup on new server and start making changes in spfile and pfile and go for changes ??
