Upgrade path from 3.9 to 4?

[GeoffA]

Welcome to Rockstor @twermann

The journey from 3.9 to 4 is a fresh install and the underlying Linux distros are different (CentOS for v3 vs opensuse for v4).

However there is no official v4 installer available yet, but you can build your own from the latest beta version:

Rockstor 4 Installer Recipe - call for beta testers

I am somewhat relieved, and a little surprised, to finally be announcing our new installer recipe. And I would like to call on those interested to ‘check our workings’. We do not yet have a binary download of the resulting installer as we must first ensure we are finalised on what it is we intend to be distributing in binary form in the first place. This new repository release, and this forum threads/request, is all part of that process. So please visit the above repo and try out the instruct…

I have gone through this build before: it is quite straightforward.

Your existing v3.9 data pools and config can be imported into v4. I trust you have effective and current data backups. When installing v4, I’d suggest a fresh target disk, and disconnect all the data pools. After install is complete, shutdown, reconnect data drives and reboot.

Good luck!
