Will Creating a New Xbox/Microsoft Account Delete Game Data?

Yes. Game saves, achievements, licenses, and subscriptions are bound to your Microsoft account (Xbox Live profile). A new account = blank slate.

What You Lose

• All cloud saves (unless backed up externally).
• Digital licenses (games/DLC) — cannot transfer purchases.
• Gamerscore, achievements, friends list, clubs.
• Xbox Game Pass / Gold subscription time.

How to Keep Data When Switching Consoles

1. Sign in with your existing Microsoft account on the new Xbox.
2. Enable Cloud Sync (Settings → System → Backup) — saves upload automatically.
3. For disc games, just insert; progress syncs from cloud.

If You Must Change Accounts

• Some games (e.g., Minecraft Bedrock, Fortnite) link progress to a separate Epic/Mojang account — link that first.
• Contact Xbox Support; they rarely merge accounts (only for enforcement errors).

Bottom line: never create a new account unless the old one is permanently lost.
