I genuinely don't understand the problem here.
You just need to update your team to the latest version all at the same time. Problem solved.
In all your posts, you haven't given any reasons why that wouldn't work. So I'm just completely mystified as to why you are still asking about this.
As I said: people who stay on old versions routinely run in to all sorts of bugs, compatibility issues, performance pitfalls and other problems that we've already fixed. This needlessly increases our support burden as people end up filing issues and contacting support about problems which were already solved. This wastes everyone's time, and is particularly painful for us as a small team with already very limited resources. We want to avoid that, so we auto-update everyone, and I think we have an extremely good track record with backwards compatibility.
