# kava-10 Upgrade Instructions
## Software Version and Key Dates
- We will be upgrading from chain-id "kava-9" to chain-id "kava_2222-10".
- The version of Kava for kava-10 is v0.17.3
- The kava-9 chain will be shutdown with a `SoftwareUpgradeProposal` that activates at block height **1610471**, which is approximately 15:00 UTC on May, 25 2022.
- kava-10 genesis time is set to May 25, 2022 at 17:00 UTC
- The version of cosmos-sdk for kava-10 is v0.45.3
- The version of tendermint for kava-10 v0.34.19
- The minimum version of golang for kava-10 is **1.17+**.
### Risks
As a validator, performing the upgrade procedure on your consensus nodes carries a heightened risk of double-signing and being slashed. The most important piece of this procedure is verifying your software version and genesis file hash before starting your validator and signing.
The riskiest thing a validator can do is discover that they made a mistake and repeat the upgrade procedure again during the network startup. If you discover a mistake in the process, the best thing to do is wait for the network to start before correcting it. If the network is halted and you have started with a different genesis file than the expected one, seek advice from a Kava developer before resetting your validator.
### Recovery
Prior to exporting kava-9 state, validators are encouraged to take a full data snapshot at the export height before proceeding. Snap-shotting depends heavily on infrastructure, but generally this can be done by backing up the .kava directory.
It is critically important to back-up the .kava/data/priv_validator_state.json file after stopping your kava process. This file is updated every block as your validator participates in consensus rounds. It is a critical file needed to prevent double-signing, in case the upgrade fails and the previous chain needs to be restarted.
In the event that the upgrade does not succeed, validators and operators must downgrade back to v0.16.x of the Kava software and restore to their latest snapshot before restarting their nodes.
## Upgrade Procedure
### Before the upgrade
Kava Labs has submitted a `SoftwareUpgradeProposal` that specifies block height **1610471** as the final block height for kava-9. This height corresponds to approximately 15:00 UTC on May 25th. Once the proposal passes, the chain will shutdown automatically at the specified height and does not require manual intervention by validators.
### On the day of the upgrade
**The kava chain is expected to halt at block height **1610471**, at approximately 15:00 UTC, and restart with new software at 17:00 UTC May 25th. Do not stop your node and begin the upgrade before 15:00 UTC on May 25th, or you may go offline and be unable to recover until after the upgrade!**
**Make sure the kava process is stopped before proceeding and that you have backed up your validator**. Failure to backup your validator could make it impossible to restart your node if the upgrade fails.
1. Export State (this **MUST** be done using **v0.16.x**)
```sh
# verify version before export:
kava version --long
# name: kava
# server_name: kava
# version: 0.16.0 (any 0.16 version is fine)
# commit: 184ef2ad4127517828a4a04cc2c51594b66ac012
# build_tags: netgo,ledger
# go: go version go1.17.1 linux/amd64
# export genesis using v0.16.x
kava export --for-zero-height --height 1610471 > export-genesis.json
```
**Note:** This can take a while!
2. Update to kava-10
```sh
# in the `kava` folder
git pull
git checkout v0.17.3
make install
# verify versions
kava version --long
# name: kava
# server_name: kava
# version: v0.17.3
# commit: [TBD]
# build_tags: netgo,ledger
# go: go version go1.17.1 linux/amd64
# Migrate genesis state
kava migrate export-genesis.json > genesis.json
# Verify output of genesis migration
kava validate-genesis genesis.json # should say it's valid
kava assert-invariants genesis.json # should say invariants pass
jq -S -c -M '' genesis.json | shasum -a 256
# 3bc9829faf3beae2892ff1dfb7158f41a3f0cff303b4798777a559250a4dc815
# Restart node with migrated genesis state
cp genesis.json ~/.kava/config/genesis.json
kava tendermint unsafe-reset-all
# Update app.toml - see section below
# Restart node -
# ! Be sure to remove --halt-time flag if it is set in systemd/docker
kava start
```
kava v0.17 requires changes to app.toml:
- There are 3 new sections - `evm`, `json-rpc`, `tls`. see the [default app.toml](app.toml)
- There is one addition to Base Configuration: `iavl-cache-size`.
- It is recommended to add a min gas price for evm txs in `akava` (where 1ukava = 10^12akava). eg `minimum-gas-prices = "0.001ukava;1000000000akava"`
kava v0.17 requires changes to config.toml:
- Depending on your setup, you will need to update the `seeds` and/or `persistent_peers` values in config.toml. These can be found [here](https://docs.google.com/spreadsheets/d/1s3LXLPFJazzdmwKdRv909pe_-ZV_Xbt2uCCNrhoOyIE).
### Coordination
If the kava-10 chain does not launch by May 25, 2022 at 21:00 UTC, the launch should be considered a failure and validators should refer to the [rollback](./rollback.md) instructions to restart the previous kava-9 chain. In the event of launch failure, coordination will occur in the [Kava discord](https://discord.com/invite/kQzh3Uv).

# Kava-10 Rollback Instructions
In the event that the Kava-10 relaunch is unsuccessful, we will restart the Kava-9 chain using the last known state.
In order to restore the previous chain, the following data must be recovered by validators:
- The database that contains the state of the previous chain (in ~/.kava/data by default)
- The priv_validator_state.json file of the validator (in ~/.kava/data by default)
If you don't have the database data, the Kava developer team or another validator will share a copy of the database via Amazon s3 or a similar service. You will be able to download a copy of the data and verify it before starting your node.
If you don't have the backup priv_validator_state.json file, you will not have double sign protection on the first block. If this is the case, it's best to consult in the validator discord before starting your node.
## Restoring state procedure
1. Stop your node
```sh
kava stop
```
2. Copy the contents of your backup data directory back to the $KAVA_HOME/data directory. By default this is ~/.kava/data.
```sh
# Assumes backup is stored in "backup" directory
rm -rf ~/.kava/data
mv backup/.kava/data ~/.kava/data
```
3. Install the previous version of kava
```sh
# from kava directory
git checkout v0.16.1
make install
## verify version
kava version --long
```
4. Start kava process
```sh
### be sure to remove --halt-time flag if it is set
sudo systemctl daemon-reload
sudo systemctl start kava
```
