RHEL upgrade - queries - EBS R12.2

[satish]

Dear erman,

We have RHEL 7.9 and ebs version R12.2.5 with 2 node DB 19.17 RAC.

We have 2 node shared application tier with GFS cluster.

Linux team is planning to upgrade to RHEL 8.

Is in place upgrade possible in this case?
What precautions should we take from apps team?

Pls kindly share your expertise.

Thanks,
SG

For complex environments, a staged migration approach may be safer.
For in place upgrade ; you have to be aligned with EBS, GRID and RDBMS.. (in terms of compatability)
