-## Option 1: Using the Staking dApp
+1. Create a new validator
 
 The Staking dApp offers a user-friendly interface for creating a new validator on the BNB Smart Chain. Follow the
 detailed instructions in the [validator creation guide](creation.md) to set up your new validator. It's crucial to
 populate the `Identity` field as specified in the guide to ensure a successful migration.
 
+2. Migrate stakes to the new validator

 Once your new validator is active, inform your delegators about the migration. They will need to migrate their stakes to
 your new validator to continue supporting you. For comprehensive details on stake migration, refer to
-the [stake migration guide](../users/stake-migration.md).

-process for validator operators. Follow the [provided steps](https://github.com/bnb-chain/bc-migration-tool) to use the
