Please make note to confirm if the clean_requirements_on_remove is turned off in your environment before proceeding with the upgrade.

grep 'clean_requirements_on_remove' /etc/yum.conf

Set to 0 to turn off and run 'yum clean all' before proceeding


If this config was enabled during upgrade and receiving the following error, please use this solution

'rpm -q postgresql93 postgresql93-libs postgresql93-server' failed(2)

I'm confused, from the release notes:
"Postgres SQL Upgrade (CB-21420)
1. Postgresql93 should be installed during first service startup after 6.2.4 upgrade."
Isn't Postgresql 9.3 already installed? Do you mean Postgresql 10? Because the server admin reported that postgresql was updated to 10.

@nverrill, posgres93 is installed in versions prior to 6.2.4. When you upgrade to 6.2.4 we want postgres93 to still be installed. When you run /usr/share/cb/cbupgrade our scripts will do an automated migration to postgres10. If postres93 is not installed when trying to run /usr/share/cb/cbupgrade, the migration will not be able to start and thus you will be in a situation where the services will not be able to start. 

Both will technically be installed, however after migrations and services have successfully started, you can then remove postgres93 and files.

 If you do find yourself in a situation where postgres93 is uninstalled before cbupgrade was run, you can use the following to workaround the issue.


Thank you,
