+# dPoW 0.8.2 update information
+
+### Update Litecoin Core to `v0.21.4`
+
+The main purpose of this update is to upgrade the outdated Litecoin Core `0.16.x`, still used on notaries, to the latest version `v0.21.4`. Since a resync is required (as explained [here](https://github.com/litecoin-project/litecoin/issues/865#issuecomment-1304798606)) when updating from pre-MWEB versions, we need to prepare in advance. Specifically, build the latest `litecoind` and perform a full sync from scratch before the transition. The manual below explains how to achieve this without losing notarization counts and without stopping LTC notarizations.
+
+#### Build latest Litecoin:
+
+```bash
+cd ~
+git clone https://github.com/litecoin-project/litecoin litecoin.021
+cd litecoin.021
+git checkout beae01d # https://github.com/litecoin-project/litecoin/tree/v0.21.4
+# apply patches from PR#990 to build dependencies with gcc-11
+wget https://github.com/litecoin-project/litecoin/pull/990.diff
+git apply -v 990.diff
+# build as described here https://komodoplatform.com/en/docs/notary/
+make -C ${PWD}/depends v=1 NO_PROTON=1 NO_QT=1 HOST=$(depends/config.guess) -j$(nproc --all)
+./autogen.sh
+CXXFLAGS="-g0 -O2" CONFIG_SITE="$PWD/depends/$(depends/config.guess)/share/config.site" ./configure --disable-tests --disable-bench --without-miniupnpc -enable-experimental-asm --with-gui=no --disable-bip70
+make V=1 -j$(nproc --all)
+```
+
+#### Sync latest Litecoin from scratch:
+
+```bash
+mkdir -p ~/.litecoin.021
+echo -e "txindex=1\nrpcport=9334\nserver=1\nlisten=0" > ~/.litecoin.021/litecoin.conf
+./src/litecoind -datadir=$HOME/.litecoin.021 -daemon
+tail -F ~/.litecoin.021//debug.log # sync monitoring, when it synced till 100%, stop it
+./src/litecoin-cli -datadir=$HOME/.litecoin.021 stop
+rm ~/.litecoin.021/litecoin.conf
+```
+
+#### Swap data folders and sources folders:
+
+```bash
+cd ~
+~/litecoin/src/litecoin-cli stop && sleep 5 # stop your old daemon
+cp ~/.litecoin/litecoin.conf ~/.litecoin.021 # copy .conf and wallet.dat in new folder
+cp ~/.litecoin/wallet.dat ~/.litecoin.021
+mv ~/.litecoin ~/.litecoin.016 # swap folders
+mv ~/litecoin ~/litecoin.016
+mv ~/.litecoin.021 ~/.litecoin
+mv ~/litecoin.021 ~/litecoin
+```
+
+#### Start the new litecoin daemon
+
+Start `litecoind` as usual. If you use scripts to start all daemons, modify them to include the `-daemon` argument to prevent console spam, and remove the `-pubkey` argument, as `litecoind` does not recognize it and will quit shortly instead of launching. Your daemon launch command should look like this: 
+
+```bash
+~/litecoin/src/litecoind -daemon
+```
+
+### Restart Iguana
+
+```bash
+# Update dPoW repo
+cd ~/dPoW
+git checkout master
+git pull
+
+# Restart Iguana
+pkill -9 iguana
+cd iguana
+./m_notary_build
+./m_notary_main
+```
+
+Make sure notarisations are progressing.
