+# Sync From Scratch 
+
+
+Because of breaking changes we made with release 10001 rc7, the node should be synced with `injectived`
+version 10001 rc6, until halt height block 2045750. Then the `injectived` binary should be updated to version 10001 rc7 to the latest block.
+
+Here is a simple 6-step guide on how to sync from scratch. 
+
+
+### Step 1
+
+Backup your configuration
+
+```
+mkdir $HOME/injectived-backup/
+cp -rf $HOME/.injectived/config $HOME/.injectived/keyring-file $HOME/injectived-backup/
+```
+
+### Step 2
+ Get the previous release version `10001 rc6`
+ ```
+ # Make sure that no running injectived processes
+ killall injectived &>/dev/null || true
+ 
+ # Remove current binary that you use 
+ rm -rf /usr/bin/injectived 
+ 
+ wget https://github.com/InjectiveLabs/injective-chain-releases/releases/download/v1.0.1-1629427973/linux-amd64.zip
+ 
+ unzip linux-amd64.zip
+ 
+ mv -f injectived /usr/bin
+ 
+ #check version
+ injectived version 
+ 
+ # Should output
+ #Version dev (48356b9)
+ ```
+
+### Step 3
+Init chain
+```
+# The argument <moniker> is the custom username of your node. It should be human-readable.
+export MONIKER=<moniker>
+
+# the Injective Chain has a chain-id of "injective-1"
+injectived init $MONIKER --chain-id injective-1
+```
+
+### Step 4 
+Sync to halt height block
+``` 
+injectived start --halt-height 2045750
+```
+
+The node will automatically exit upon reaching block height reachs 2045750. 
+
+**NOTE:** The sync process takes approximately two days until it reaches halt height. If you want to run sync as a background process, follow the official guide [using systemd service][using-systemd-guide-link].
+**Make sure you update ExecStart commannd** bypassing `--halt-height 2045750` param.
+ Otherwise, you will overshoot the halt height and will have to resync from scratch again.
+
+`ExecStart=/bin/bash -c '/usr/bin/injectived  --halt-height 2045750 --log-level=error start'`
+
+
+### Step 5 
+From this step, given that you've now reached the halt height, you can now switch binary to the latest version.
+
+```
+# Make sure that no running injectived processes
+killall injectived &>/dev/null || true
+
+# If you use systemd service, stop it, otherwise skip this step
+sudo systemctl stop injectived && sudo systemctl disable injectived
+
+# Remove old binary, you don't need it anymore
+rm -rf /usr/bin/injectived 
+
+# Get the latest one
+wget https://github.com/InjectiveLabs/injective-chain-releases/releases/download/v1.0.1-1630308393/linux-amd64.zip
+
+unzip linux-amd64.zip
+
+sudo mv injectived peggo injective-exchange /usr/bin
+#check version
+injectived version 
+ 
+# Should output
+#Version dev (b174465)
+```
+
+### Step 6
+Continue syncing to the latest block.
+
+```
+injectived start
+```
+
+**NOTE:** If you want to continue sync as a background process, follow the official guide [using systemd service][using-systemd-guide-link].
+**Make sure you update back ExecStart commannd** by removing `--halt-height 2045750` param.
+
+
+`ExecStart=/bin/bash -c '/usr/bin/injectived --log-level=error start'`
+
+
+Start systemd service
+
+`sudo systemctl start injectived && sudo systemctl enable injectived`
+
+
+Wait until the sync finishes, and the block height should reach the latest chain block. Follow via API
+
+```
+curl localhost:26657/status | grep height
+```
+
+When it reaches network block height, your node is fully synced, and you are running the latest version of the injective chain.
