You should always move to a newer kernel, what is holding you back from
doing that today?  Please, move to 4.14.y if you want a "LTS" kernel to
survive you for the year, and if not, then use 4.15.y please.

Seriously, staying on old kernels should not happen, unless you are
paying someone for support of such a thing (i.e. you have specific
hardware support only for an old kernel version.)
