Introduction

SushiSwap’s V3 introduces concentrated liquidity, custom fee tiers, and more refined control for liquidity providers. :contentReference[oaicite:0]{index=0} If you currently hold positions in V2, migrating to V3 might bring better capital efficiency—but it also introduces new complexity. This guide will walk you through the migration process step by step, highlight security best practices, address troubleshooting, and answer common user questions.

Step 1: Review V3 Features & Differences

Before migrating, understand what changes in V3:

• Concentrated Liquidity: You must choose a price range where your capital will be active. :contentReference[oaicite:1]{index=1}
• Custom Fee Tiers: Multiple fee levels (e.g. 0.05%, 0.30%, 1.00%) allow more flexible risk/reward choices. :contentReference[oaicite:2]{index=2}
• NFT Positions: In V3, each liquidity position is represented as an NFT you can manage or transfer. :contentReference[oaicite:3]{index=3}

Step 2: Prepare Your V2 Liquidity for Removal

• Go to SushiSwap V2 UI and locate your LP position.
• Unstake or withdraw any rewards or incentives first.
• Remove your liquidity from the V2 pool (this returns your underlying tokens).
• Ensure your wallet has enough ETH (or the chain’s native token) for gas fees.

Step 3: Migrate to V3 Safely

• Visit the official SushiSwap V3 migration or “Migrate Liquidity” interface (check docs at Sushi V3 docs). :contentReference[oaicite:4]{index=4}
• Select the tokens you withdrew from V2 that correspond to the V3 pool you intend to join.
• Choose an appropriate price range and fee tier for your V3 liquidity. Be cautious—too narrow a range may lead to underutilization.
• Approve token transfers for the migration contract (only the amount you intend to migrate, avoid unlimited approvals).
• Confirm the migration transaction in your wallet. Once processed, your liquidity will be moved into a new V3 NFT‑based position.

Security Best Practices

• Only use official SushiSwap links and documentation to avoid phishing risks.
• Limit contract approvals—avoid granting unlimited allowance where possible.
• Use hardware wallets to ensure your private keys remain offline.
• Check that the migration contract is audited and known (cross-check contract addresses with official docs).
• Start migrating small amounts first to test the process before doing large migrations.

Troubleshooting Common Migration Issues

Always test with small migrations first and stay informed by checking official SushiSwap documentation. :contentReference[oaicite:5]{index=5}
