What is the best way to migrate an established install from nightlies to Beta?
As described in Updating and downgrading your system, you just change the repo URLs and “update”.
Note, if you switch back from a newer nightly to the beta1, you should do a “pkgman full-sync” instead of a “pkgman update” so packages also get downgraded to an earlier version.
Ah thanks. I was looking in the installed user guide. This document is much more convenient than going to the website for documentation. Especially handy for offline systems and broken network situations.
