Hey gang - so I’ve got a 5inch drone running betaflight 4.3 - and I’m very happy with it, and I’d love to leave it on 4.3.
I’m now building a 7inch LR drone, and I fancy using betaflight 4.4 or maybe 4.5.
Will I have to upgrade my configurator to use 4.4 or 4.5? and will this screw up the configuration of 4.3 on my 5inch drone?
Or can I run 2 configurators?
BFL configurators are backwards compatible so if you upgrade to 4.5 for your new 7” you should be OK to use it for your 4.3 5”er
Ahhh this is good news!
Would i simply download the new configurator and dutch the old one?
Aaaand. Is BF 4.5 fully functional and trusted?
Yes 
Can’t say, I’m not a big BF user, these guys will know…

other experts are available LOL
Yep as far as I am aware.
4.6 looks like some interesting features as well.
