Yan Xu commented on MESOS-7714:
-------------------------------
Great. I guess I am just not clear on the mechanism to achieve that.
Downgrading currently fails [the CHECK
here|https://github.com/apache/mesos/blob/1.3.0/src/slave/paths.cpp#L478] for
me (from a 1.4 agent with persistent volumes). It looks like the proposal is to
commit some downgrading logic to 1.3.x branch? Sorry it's not clear to me if
the case I am mentioning is covered.

> The agent code only partially supports downgrading of an agent correctly.
> The checkpointed resources are done correctly, but the resources within
> the {{SlaveInfo}} message as well as tasks and executors also need to be
> downgraded
> correctly and converted back on recovery.
