Migrate IRISHub to v1.0.0 from v0.16.3

1. Export genesis file

Stop irishub v0.16.3 daemon and use irishub v0.16.3 to export mainnet state genesis with --for-zero-height at the upgrade block height

iris export --home [v0.16.3_node_home] --height [upgrade-height] --for-zero-height

2. Migrate genesis file

Migrate the exported genesis.json with irishub v1.0.0

iris migrate genesis.json --chain-id irishub-1 > genesis_v1.0.0.json

Check if md5 is correct

md5sum genesis_v1.0.0.json

3. Initialize new node

Initialize the new node with irishub v1.0.0

iris init [moniker] --home [v1.0.0_node_home]

4. Migrate privkey file

Migrate privkey file with irishub v1.0.0

go run migrate/scripts/privValUpgrade.go [v0.16.3_node_home]/config/priv_validator.json [v1.0.0_node_home]/config/priv_validator_key.json [v1.0.0_node_home]/data/priv_validator_state.json

5. Migrate node key file

Migrate node key file with irishub v1.0.0

cp [v0.16.3_node_home]/config/node_key.json [v1.0.0_node_home]/config/node_key.json

6. Copy migrated genesis file

Copy genesis_v1.0.0.json to new node home

cp genesis_v1.0.0.json [v1.0.0_node_home]/config/genesis.json

7. Config new node

Configure minimum-gas-prices in [v1.0.0_node_home]/config/app.toml

# The minimum gas prices a validator is willing to accept for processing a
# transaction. A transaction's fees must meet the minimum of any denomination
# specified in this config (e.g. 0.25token1;0.0001token2).
minimum-gas-prices = "0.2uiris"

Copy persistent_peers in [v0.16.3_node_home]/config/config.toml to [v1.0.0_node_home]/config/config.toml

# Comma separated list of nodes to keep persistent connections to
persistent_peers = ""

And configure other fields refer to [v0.16.3_node_home]/config/config.toml

8. Start new node

Start new node with irishub v1.0.0

iris unsafe-reset-all --home [v1.0.0_node_home]
iris start --home [v1.0.0_node_home]
