OpenSuse 13.2 and Leap 42.1 ongoing

From what I can read about Leap 42.1, it seems to follow a different OpenSuse distribution path than 13.2. Is this correct ?

Are both these paths ongoing, in that new releases of OpenSuse will be offered separately on each path ?

Or is all OpenSuse ongoing distributions going to follow the Leap path ?

Ther will be no 13.3 if it is that what you mean. Next version will be something like 42.2 (I am not sure, but I think that is more or less guessing for everybody). And after some time 13.2 will be dropped from support.

Roughly speaking, Tumbleweed is following the 13.2 path. But it’s a rolling distribution. It seems unlikely that there will be a 13.3 (i.e. freezing Tumbleweed at some point). You are right, that 42.x is something of a separate path, with more emphasis on stability. And it’s a bit closer to the enterprise SUSE release.

However, the two paths are not totally independent. At least as I understand it, Tumbleweed is the bleeding edge version, and much of what is seen there will eventually filter into 42.x.

And now it’s time for me to update my Tumbleweed installation.

Does this mean that as long as I remain on 13.2, and continue to download the latest updates using Yast, I am getting the latest changes from Tumbleweed ? That is what I want as I want to continue, as a developer, working with the bleeding edge from Tumbleweed whenever it is available.

ah no, 13.2 was based on TW at the time it was released and continues to get security patches and some updates (mostly from packman and unofficial from some extra repo’s) LEAP is based on a mixture of SLE and TW.
Because of LEAP’s release 13.2 lifetime was increased and it will be 2 months after 42.2’s release while 42.1 will be supported 6 months after 42.2’s release, 42.2 should be out in october so 13.2 will be alive until december.
You can stay on 13.2 until 42.2 is released and then migrate to 42.2 you can skip 42.1, the bad news is 13.2 will be the last stable opensuse that has a 32bit release, unless things change the only supported 32bit opensuse will be TW.

So the only way I can stay up to date with the latest OpenSuse changes is to upgrade from 13.2 to Leap ? Or is there another upgrade path ?

if you want a stable distribution then yes, that’s the only way.
If you are brave of heart and don’t mind a bleeding edge rolling distro there is always TW

Is there a way to upgrade from 13.2 to TW, or must I install TW separately ?

first of all LEAP is closer to 13.2 then TW, TW is a rolling distro that means each week you get a new OS that’s the reason why there are no prebuild nvidia and ati drivers for TW and after each kernel update you’ll have to recompile the video drivers.
that being said yes there is an easy way to move from 13.2 to tw,
remove all 3rd party packages like nvidia/ati video drivers, remove all extra repo’s you should only have the OSS and Update repo’s, change the repo url’s to point to TW instead of 13.2 and then simply execute

moving to LEAP is the same, remove old drivers, remove extra repo’s, change repo’s to point to LEAP and do

just keep in mind that LEAP is basically 13.3 with code and support from SLE (this is a good thing)
