How to properly upgrade to latest version of Cacti

[armitage318]

Hi, I am using official Debian package of cacti (version 1.2.24).
I have many PHP errors in cacti.log, and I read it is recommended to upgrade to 1.2.27
How would you do this?
Remove Debian package, and then install 1.2.27 through sources (by keeping config.php of course)?
Thank you!

After backup install new debian package and go to cacti web, there will be update wizard
