+# Validator Upgrade Guide for laconic_81337-5 Testnet v0.6.0 -> v0.7.0
+
+This guide assumes you have followed the instructions to crete a systemd service or docker container validator node v0.6.0 and you perform the upgrade on a machine running v0.6.0
+
+It is highly recommended to make the backup of your datadir after you stop v0.6.0 and before you start v0.7.0. Unless you changed your datadir, it should be located in `~/.laconicd`
+
+## Systemd service
+Skip this section if you use docker
+
+This is very similar to building v0.6.0. We keep v 0.6.0 running until v0.7.0 is built and only after the successful build we should replace 0.6.0 binary with v0.7.0. This is to avoid jailing your validator for long downtime.
+The general upgrade plan is the following:
+  1. Install Go v1.19.5 (we used 1.18 for v0.6.0)
+  2. Remove old copy of the github repository and build directory
+  3. Download the latest laconicd repository and checkout v0.7.0
+  4. Build laconicd binary (but not install in this moment)
+  5. Stop laconicd systemd service
+  6. Install recently built new version of laconicd
+  7. Start laconicd service
+
+>***You have ~10 minutes after step 5 to complete steps 6 and 7 before your validator is jailed for downtime. Getting jailed for downtime is not a disaster, however would require manual unjailing.***
+
+
+
+### Install Go 1.19
+
+```sh
+# Update Ubuntu
+sudo apt update
+sudo apt upgrade -y
+
+# Install required software packages
+sudo apt install git curl build-essential make jq -y
+
+# Remove any existing installation of `go`
+sudo rm -rf /usr/local/go
+
+# Install Go version 1.19.5
+curl https://dl.google.com/go/go1.19.5.linux-amd64.tar.gz | sudo tar -C/usr/local -zxvf -
+
+```
+
+Check the version of go installed
+
+```sh
+go version
+
+# Should return something like: go version go1.19.5 linux/amd64
+```
+
+---
+
+### Remove old copy of `laconicd` build
+
+>Attention should be paid that the directory mentioned below is `~/laconicd` and NOT `~/.laconicd`. The latter is the data directory containing all your node data and configuration and it must be kept during the upgrade.
+
+```sh
+# Remove the previous build directory
+cd ~
+rm -rf laconicd
+```
+
+---
+
+### Download `laconicd` repository
+```sh
+git clone https://github.com/cerc-io/laconicd.git
+cd laconicd
+
+# Checkout 0.7.0 branch
+git fetch --all
+git checkout v0.7.0
+```
+
+---
+
+### Build the new version of `laconicd`
+
+```sh
+# Build laconic (but not install at this moment)
+make VERSION=v0.7.0 build
+```
+
+---
+
+### Stop `laconicd` systemd service
+
+```sh
+sudo systemctl stop laconicd
+```
+
+>***Make sure the service is stopped***
+
+```sh
+sudo systemctl status laconicd
+```
+
+---
+
+### Install new `laconicd` version
+
+```sh
+make VERSION=v0.7.0 install
+```
+
+Verify your installation
+
+```sh
+laconicd version
+```
+This should return `0.7.0`
+
+---
+
+### Start `laconicd` systemd service
+
+```sh
+sudo systemctl start laconicd
+```
+
+Verify that the node joined the network and produces new blocks
+
+```sh
+journalctl -f -u laconicd
+```
+
+
+---
+
+## Docker container
+
+Upgrade plan:
+  1. Stop running v0.6.0 container
+  2. Delete v0.6.0 container
+  3. Create v0.7.0 container
+  4. Start v0.7.0 container
+
+>***You have ~10 minutes to complete the upgrade procedure before your validator is jailed for downtime. Getting jailed for downtime is not a disaster, however would require manual unjailing.***
+
+### Stop running v0.6.0 container
+```sh
+docker stop laconic-testnet-5
+```
+
+---
+
+### Delete v0.6.0 container
+```sh
+docker rm laconic-testnet-5
+```
+
+---
+
+### Create v0.7.0 container
+```sh
+docker create --name laconic-testnet-5 \
+--restart always \
+-v ~/.laconicd:/root/.laconicd \
+-p 26656:26656 \
+-p 127.0.0.1:26657:26657 \
+-p 127.0.0.1:26660:26660 \
+git.vdb.to/cerc-io/laconicd/laconicd:v0.7.0 \
+laconicd start --gql-playground --gql-server --log_level=warn
+```
+
+---
+
+### Start v0.7.0 container
+```sh
+docker start laconic-testnet-5
+```
+
+Verify that the node joined the network and produces new blocks
+
+```sh
+docker logs -f laconic-testnet-5
+```
