Can A World Made By Cracked Accounts Be Opened by Official Accounts?

I've been creating tons of builds in my Aternos server, but the thing is I'm using cracked Minecraft. Can I retrieve my world/server and the builds inside it if I use official Minecraft in the future? My friend who uses official Minecraft made a server and I was able to join, but we cannot see each other, so I was wondering if my builds will be saved.
