not sure if this is the right place to aks but how compatible is one dnd to 5e

so ive own the main 3 5e books for a few years know but inv never real had the chance to actually play the game but iv recently gotten the one dnd start set and i just have to ask how compatible are 5e and one dnd iv'e heard they are but I'm sceptical how compatible are they? 

edit: i mean how compatible are they are the rules trying to mess up each other ( apparently cant swear)as in is it a dumb idea to try and mix them because i have the 5e books and don't want to buy the new ones

ok but will i have to get the updated books?

ok got it il probably stick with the 2014 rules unless i realy like a new rule but im still using the starter set at least once i did spend money on it after all but anyway thanks

 Where'd you get that "one dnd start set"? 

As far as I know, a new Starter Set for the revised rules is coming in 2025: D&D Direct Recap: A Look at Two Forgotten Realms Books, a Dragon Anthology, and More

So the current Starter Set still uses the 2014 rules. The same for the Essentials Kit.

i have the storm wreck isle one i knows its  not the old starter set and since i saw a picture of it in relation to the new rules i just assumed it was for them but if I'm wrong that makes it so much easier so please do tell me if im write or wrong on that does the dragon of the storm wreck isle use the 2014 or the 2024 rules??

 Oh, ok. Thanks for your answer.

Dragons of Stormwreck Isle uses the 2014 rules, yes.

ok thats great thank both you and the other guy i got it to help lure the people im playing with in but i was worried about any rules shock since as the dm id run with 2014 rules but since the starter set runs on 2014 rules that makes everything easer so thanks :)

 You're welcome! I hope everyone has a great time playing! ;)

Our game is 2014 rules but allows 2024 character creation and spells along with 3rd party content. Working fine.
