Affects Version/s: 4.0
Fix Version/s: None
Operating System: Linux
Here are the things I had in mind about that currently:
this is a different approach than quiescing, as the version is switched even if some
people are still using the old version, the sessions are forwarded to the new version.
I think there is a limit to the session preservation:
it depends on how much different are the sessions of the two versions being switched ;
how would we handle that case:
- do we just let things happen and if the versions are too much different this might
involve some unexpected behavior,
- or do we figure out if the two versions are compatible each other to preserve their
sessions and prevent the switch if they are not compatible?
