adjust breakouts after rooms opened

[shaunr]

I want to use the adjust breakouts after the rooms have been opened mentioned in 5.9.3  

But it says that end users must have 5.9.3 and if they don't they can't even use the meeting?

many of our users struggle at upgrading and some can't do it.  

So this would be very good as we want to delete some empty rooms as roosm end at different times and persons come late and choose a room option is good   .  we don't want persons to waste time comeing to empty room.

However, the requirement to 5.9.3  would be a problem and we can't use.

Why is 5.9.3 required anyway?  

Will this change in the future?
