I've spent most of my life on Debian Linux.
Updating to the chosen version is incredibly simple.
A small change to the repository configuration entries, executing two commands:
	
	
	
		Code:
	
	
		apt update && apt dist-upgrade
	 
 And if there are no conflicts, the system will update to the release specified in the configuration.
Release 15.0-RELEASE is practically a month away, and there's no documentation on how to update the system to the specified release. If someone has already decided to switch to pkgbase (without creating a system backup using beadm), all that's left is to compile the entire system for the desired release.
I debated for a long time whether to switch to pkgbase at this stage. I decided to do so, following Vermaden's recipe: 
https://vermaden.wordpress.com/2025/07/20/freebsd-pkgbase-pkgbasify-tool/ . And since Vermaden uses it, it must be something good and sensible.
The conversion went without a hitch. But after the fact, I started wondering what to do next with the system.
What are the current mechanisms for getting the desired release? It's a good thing I made the changes on my home desktop system to see how it works 

 . So, there wouldn't be any major losses if something went wrong.
