Is it possible to upgrade an existing database server (11.2.0.4) from ol6 to ol7?
We have a number of database server instances running Oracle Linux 6.9 (latest) with the UEK4 kernel supporting Oracle DB 11.2.0.4 that we'd like to upgrade to OL7.
Oracle does have an upgrade document:
https://docs.oracle.com/cd/E52668_01/E93593/html/ol7-upgrade-ol6.html
However I note these conditions:
It is possible to upgrade an Oracle Linux 6 system to Oracle Linux 7 Update 5 under the following conditions:
- The system meets the minimum installation requirements for Oracle Linux 7 as described in Chapter 1, System Requirements and Limits.
- The Oracle Linux 6 system has been completely updated from the
ol6_x86_64_latest
channel orol6_latest
