Downgrade Apache to last installed version

The last time I updated Apache (2.4.23--> 2.4.25) it causes some trouble at midnight and I found out the next morning. I had to hire someone to fix it to 2.4.23 again. And he did it pretty fast.
I see version 2.4.27 waiting to be installed but I'm a bit worried since my last Apache update...

Can I do this "rollback" myself easily? Is it a general Custombuild functionality, or CentOS 7 functionality or is it "just" downloading en installing the previous version again?

Fairly easy.

You can fill in Apache there too and the version number.
It might be needed afterwards to run ./build rewrite_confs from the custombuild directory.

But it would also be good to note errors and try to solve why they occur.
