Does it make sense to continue support of 2.4Ghz, when all devices support 5ghz?

Even if all your issued devices support 5 Ghz, and I mean all - including random things like security cameras or WiFi thermostats, guest networks probably still need 2.4 GHz for now. There are a lot of older phones still in use with 2.4Ghz only.

With questions like this, it always depends on the environment. Typically, an increase of frequency will decrease range, i.e. a 2.4 GHz radio will theoretically cover a larger area than an equally powered 5 GHz radio, thus you may be able to cover a larger area with fewer access points. Construction variables, however may attenuate a signal at 2.4 GHz more than at 5 GHz.

Site surveys and testing are the best bet.

Best,

If you can get away with 5 only, great! But you're going to have to test in your own environment, as the other posters are saying.
