Description:
- Dist upgrade to full fledged migration status.
- Online migration should be supported from 11.1 to 11.2
+ With the 11.2 cycle, we want to offer users the ability to perform a
+ live system upgrade in the manner of Debian's dist-upgrade.
+ For the purpose of this cycle, we want to support dist-upgrade from the
+ previous version (11.1) only, as this is a sufficiently complicated
+ problem as is.
+ From the user's view, the difference is between being able to update
+ the system incrementally within the given version or service pack
+ running, to being ble to migrate with a system command ("zypper dup" or
+ similar) to a higher version altogether. In the Debian experience, the
+ set of base distributions is not necessarily limited, but it has been
+ Ubuntu's practice to define what starting points other than "release n-
+ 1" are allowed (for instance, all LTS versions are purported to be able
+ to "apt dist-upgrade" to the top of the line, although I have heard of
+ problems trying to jump two years - 6.06->8.10 - in a fell swoop in
+ this manner :-). In the openSUSE scope, we should aim to be able to
+ "dup" between incremental versions, starting from 11.1 to 11.2, and
+ later 11.x to 12.0.
+ Business case (Partner benefit):
+ openSUSE.org: With the introduction of the Zypper stack to SLE, we
+ finally reached the state of a featureful (which YOU was not) and fast,
+ reliable (which ZLM was not) update stack in the platform.
+ For enterprise use, some tweaks are still desirable (changelogs,
+ rollback, ...) which we are looking at, as well as improvements on the
+ Enterprise management front, which we are working on with our SRM
+ colleagues.
+ The only really significant competitive feature we are missing at this
+ point is the Debian/Ubuntu dist-upgrade functionality, which has a
+ powerful psychological impact at the Enterprise level and a much more
+ tangible impact at the small user / single user level: many with no IT
+ department do use Ubuntu these days on the basis that "chasing" Fedora
+ and openSUSE along the six-month upgrade cycle is too much for them,
+ and feel they can save time on Ubuntu with the combination of dist-
+ upgrade and the longer LTS cycle.
+ The rationale for pursuing this is to revoke the special status of
+ coolness this functionality gives Ubuntu, and to terminate the negative
+ influence that has on our SLE sales (from the expert's personal
+ opinion, the preference then spills into purchasing).

This is the #1 feature in the systems management scope for 11.2 - I
have no doubt it will be fun :-)
