## Upgrading from a previous network
These instructions are for anyone that ran a previous network and would like to upgrade to a newer version.
Remove the ephemeral files and reset the data.
```
rm $HOME/.gaiad/config/addrbook.json $HOME/.gaiad/config/genesis.json
gaiad unsafe_reset_all
```
Now your node is in a prestine state without changing your validator key. If you had any
sentry nodes or full nodes setup correctly previously they should work.
**Make sure that every node has a unique `priv_validator.json`. Do not copy the `priv_validator.json` from an old node to multiple new nodes. Running two nodes with the same `priv_validator.json` will cause you to double sign.**\
Now it is time to upgrade the software.
```
cd $GOPATH/src/github.com/cosmos/cosmos-sdk
git fetch --all
git checkout v0.18.0-rc0
make update_tools
make get_vendor_deps
make install
```
The next step is to obtain the new genesis file from `https://github.com/cosmos/testnets`.
```
cd $HOME/testnets
git pull origin master
cp -a gaia-6001/genesis.json $HOME/.gaiad/config
```
The last step is the adjust the `config.toml`. Make sure that you are connected to healthy peers or seed nodes.
These are some seeds nodes and they can be put into the config under the `seeds` key. Alternatively you can also
ask user validators directly for a persistent peer and add it under the `persisent_peers` key.
