This client includes a Frontier Database Migration, so the steps to upgrade to v0.50.0 without issues are:

1. Stop your node
2. Purge your Frontier Database
3. Upgrade the binary/Docker image
4. Start the node

The Frontier database will be reconstructed automatically from the latest block to genesis.

Here you can find how to purge your Frontier Database:

• Docker - https://docs.moonbeam.network/node-operators/networks/run-a-node/docker/
• Binary - https://docs.moonbeam.network/node-operators/networks/run-a-node/systemd/

⚠️ Breaking Changes ⚠️

• Replace --ethapi-trace-cache-duration by --ethapi-trace-cache-size (default: 104857600 bytes / 100MB) (https://github.com/moonbeam-foundation/moonbeam/pull/3616)
• The block range provided in trace_filter RPC is now bounded by default to 1024 blocks. This value can be overridden by passing --max-block-range <MAX_BLOCK_RANGE> when starting the client. (https://github.com/moonbeam-foundation/moonbeam/pull/3601)
