The attack was certainly planned meticulously and can be termed a successful operation. Even the Russian media acknowledges it so, reporting that 5 airfields were targeted, attack on 3 were repelled successfully while attacks on 2 were a partial success. But they also speculate that Ukraine will not be able to carry out such attacks any more. As per their analysis, the drones were launched from cargo trucks and remotely guided via mobile networks. The Russian military are already revising their base security doctrines to increase surveillance around the bases and will now be apparently jamming mobile signals over airbases. Moreover, such kind of attacks require a network of human operatives - many have already been arrested and counter-intelligence operations to track down the rest is already underway.

So any more future attacks of such nature would all depend on how successfully the Ukrainian operatives in Russia are able to evade Russian security services.
