Every Intel Core i3, i5, i7 etc is v2 or better, every “Core” brand newer than Core2*, which began in late 2008.
Zypper dup can be done in steps. The manual method that worked for me, meaning no installation of openSUSE-repo* rpms, done afterzypper al openSUSE-repo*, and no need for --releasever=16.0 option with zypper dup, done logged in as root, includes:
- remove from /etc/zypp/repos.d the old update repo files and replace with one containing
baseurl=http://cdn.opensuse.org/update/openSUSE-stable/repo/oss/ - update balance of content of /etc/zypp/repos.d/ from 15.6 to 16.0 with text editor
- disable optional repos
- zypper clean
- zypper ref
- zypper dup -d
- zypper dup
- re-enable any necessary optional repos
- zypper up
1 & 2 configure repos for upgrade to 16.0. 3 should be self-evident. 4 clears cache of anything that may remain. 5 updates zypp database, unnecessary if all repos are configured to auto-refresh. 6 downloads all packages to be installed. 7 does the actual upgrade from the fresh new local rpm cache. 7 should go quickly, so if you have your computer connected to a UPS, interruption risk from electricity outage should be nil or less.
