Hi alex, I know that different situations calls for different measures and I understand the reason.
Y! is moving from nova-network to quantum (in-place) so I know its possible, but yes it requires pretty deep understanding of nova, quantum, packaging... Of course not everyone has the resources or expertise to do this; which to me is the void the community should be filling with tutorials, instructions... So I feel your pain! :) On 10/25/13 1:56 AM, "Alexander Stellwag" <[email protected]> wrote: >Joshua, > >On 24.10.2013 21:48, Joshua Harlow wrote: >> Whatever happened to doing in-place upgrades? >> >> Has that been problematic for u, are people just not doing it?
