How to upgrade the chain network ​

When the chain reaches a pre-designated block height the chain comes to a halt by displaying the message below.

bash
ERR UPGRADE "<version>" NEEDED at height: "<height>"
panic: UPGRADE "<version>" NEEDED at height: "<height>"

Please manually delete the chain that came to a halt with the error message.

bash
# using binary
kill -9 firmachaind

# or using system service
sudo systemctl stop firmachain

Build the binary after changing the branch that corresponds to the appropriate version.

INFO

Please check this document if you do not have the FirmaChain directory.

bash
cd firmachain
git pull
git checkout <version>
make install
sudo mv ~/go/bin/firmachaind /usr/local/bin/firmachaind

Finally, you can start the syncing process

bash
firmachaind start
