Feature changed by: Andreas Jaeger (a_jaeger) Feature #312799, revision 5 Title: Safer distribution updates - openSUSE Distribution: New + openSUSE Distribution: Evaluation by project manager Priority - Requester: Desirable + Requester: Mandatory Requested by: Michael Schröder (mlschroe) Partner organization: openSUSE.org Description: Currently the documentation says that to do a distribution upgrade you should first update your software stack to the target distribution, then do a zypper dup. The software stack update can already kill your system. zypper could allow an option that makes it first install a miniroot containing the update stack itself, then automatically switch over to the miniroot to do the "zypper dup". Use Case: - Bob wants to migrate his server from SLE12 to SLE13. Upgrading the - package management stack fails, but he keeps his original system - untouched. + Bob wants to migrate his server from SLE12 to SLE13 (or from SP1 to + SP2).
