YUM: Upgrade a package from a different repo

Question

Say I have two repos: repoa and repob. I installed a package 3.1 ver from repoa. I have a newer version 3.2 in repob.

How could I upgrade the package from repob? I tried to yum upgrade, but looks it always stick to the original repo - repoa, and didn't look at the package in repob at all. I can use 'yum provides' to get the package information from two repose, but only repoa looks recognised.

Answer 1

I tried several things such as change the priority higher for repob, temporarily remove the repoa, but none of them working.

I guess I need to remove it then do reinstallation from repob.
