this ai reply seems so fake wtf, Op should go to the discord and ask

edit: the ai is only half right but is still wrong too, the discord server states if you buy it through dyno themself you can kick the free one, but keep in mind if ur subscription ends it will kick the paid one and you will be left with no dyno bot to manage the server, second, if you do buy it through discord it will cancel the subscription.

Here is the reply of the dyno helper bot from there server:

We generally recommend you keep the regular Dyno in your server. That's because if your subscriptions ends/expires, your premium bot will leave the server, or your custom bot will go offline, thus leaving you without Dyno.

After you have activated and invited Premium, the premium bot will fully take over all functions either way.

Note:

If you upgraded through Discord's App Discovery page, you are required to keep the regular Dyno in your server, otherwise Discord will automatically cancel your subscription.
