Moving ELB between roles

There appears to be a few issues around moving ELBs between roles. For example

An ELB is assigned to Role#1. The instances from Role#1 are attached to the ELB.
A user assigns the ELB to Role#2. All of the instances from Role#1 are removed and replaced with Role#2 instances. This is expected
When viewing Role#1 in the farm configuration we see that the ELB is still shown as being attached to Role#1 even though it's been assigned to Role#2.
This shouldn't be the case, if the ELB is migrated then it should be removed from Role#1 at the same time that Role#1's instances are removed. It is misleading as it is.

What makes this worse is that if a new instance starts in Role#1 it will be added back to the ELB. This leaves the ELB with instances from both Role#1 and Role#2 attached to it.

If the expected behaviour is that an ELB can only be attached to a single role then it should be removed from Role#1 and no new Role#1 instances should be added to the ELB once the elb is assigned to Role#2.

If the expected behaviour is that multiple Roles can be attached to the ELB then the instances from Role#1 should not be removed from the ELB when Role#2 is assigned.

    HI Alan,

    Just as quick interim update - we are still looking into this with the Engineering team, and just need a bit more time.

    We’ll get back to you on this soon.
