Hi Team,
We have a requirement to migrate our existing Oracle E-Business Suite R12.2 environment to new servers with a different operating system version.
Current environment:
- Oracle EBS R12.2 with Oracle Database 19c.
- Two application servers and two database servers.
- Existing OS: Red Hat Enterprise Linux (RHEL) 7.9.
- Shared file system configuration.
Target environment:
- New single application and single database server.
- Target OS: RHEL 8.5.
No dataguard.
Downtime acceptable for 2 days.
At high level, We would like to know the recommended migration approach and the potential challenges involved in this OS migration.
Specifically:
1. Can we use the existing EBS cloning procedure (Rapid Clone) to migrate the application and database tiers to the new servers with RHEL 8.5?
2. What are the major technical challenges involved?
3. Is a direct clone from RHEL 7.9 to RHEL 8.5 supported, or would you recommend a different migration approach?
We would appreciate your high-level recommendations on the supported migration approach, prerequisites, and potential risks.
Thank you.
Satish
