Mickael Istria commented on JBDS-3085:
--------------------------------------

Having it Early Access or not doesn't change anything technically, it's just the fact that it's installed from Central that matters.
Currently, what's difficult is the concept of downgrading, that is not provided by p2/Update UI nor by discovery APIs. I believe p2 has APIs and mechanism to do that, but since it is not a usage scenario that is part of Eclipse itself, it will be difficult to find things to re-use when implementing this.
Since Eclipse itself doesn't provide downgrading operations, that means that people who install with normal Eclipse Update UI won't be able to downgrade to older version.

> *Should we be able to update JBDS 8.0.0.GA -> 8.1.0.Alpha1 via Early Access?*
> This was supposedly in the original scope for the creation of a Early Access site, but I never saw that. So, in order to get some eyeballs on this idea, and to get buy-in from QE/doc/dev/PM/PgM/PL, I'm cc:'ing some people here so we can discuss the cons and cons of this idea.

> Things to consider:
> a) what happens if an 8.0.0.GA user suddenly finds they've updated to an Alpha or Beta release? Can they uninstall? (Probably not, if they started with the installer; probably yes if they started from BYOE / Marketplace.)
> b) how will GSS support these "I was on GA but not I'm on Beta" users?
> c) What about project examples that might / might not be compatible between 8.0 and 8.x, eg., because of changes in Eclipse Luna or a new default runtime (EAP 6.3, 6.4) ?
> d) what could possibly go wrong?
