Instructions:

If you haven't upgraded yet, do the upgrade instructions then start from part 1.
If you're on block 8861810 (halted or stuck) with v1.9.1, start from part 3.
Keep pruning on "nothing" for this process, just to be safe

Part 1:

# Stop your v1.9.0 node
sudo systemctl stop secret-node

# Set pruning=nothing
perl -i -pe 's/^pruning =.*$/pruning = "nothing"/' ~/.secretd/config/app.toml

# Set halt-height to 2 blocks from now
perl -i -pe 's/^halt-height =.*$/halt-height = 8861802/' ~/.secretd/config/app.toml

# Restrat your v1.9.0 node
sudo systemctl restart secret-node

Wait for halt-height (might take a while to reach consensus)...

Part 2:

Wait for halt-height (might take a while to reach consensus)...

# Stop your v1.9.0 node
sudo systemctl stop secret-node

# Remove halt-height
perl -i -pe 's/^halt-height =.*$/halt-height = 0/' ~/.secretd/config/app.toml

# Figure out currently used db backend
DB_BACKEND=$(awk -F \" '/^db_backend =/{print $2}' ~/.secretd/config/config.toml)

# Get the v1.9.1 binaries
wget "https://github.com/scrtlabs/SecretNetwork/releases/download/v1.9.1/secretnetwork_1.9.1_mainnet_${DB_BACKEND}_amd64.deb"

# Verify the v1.9.1 binaries
echo '95b5ccb52abeae8e673445fda2cd08bfff79932f20176bf6229270c51a44c9e8 secretnetwork_1.9.1_mainnet_goleveldb_amd64.deb
632c014c934ea826f7fac563ef4f41fcd644ebe31824239069c141deda318476 secretnetwork_1.9.1_mainnet_rocksdb_amd64.deb' |
    grep "$DB_BACKEND" |
    sha256sum --check

# Install the v1.9.1 binaries
sudo apt install -y "./secretnetwork_1.9.1_mainnet_${DB_BACKEND}_amd64.deb"

# re-apply any systemd unit file customizations
Continue to step 3

At this point people stopped their nodes and we're on block 8861810 committed.

Part 3:

At this point people stopped their nodes and we're on block 8861810 committed.

# Stop your v1.9.1 node
sudo systemctl stop secret-node

# Set halt-height to 5 blocks from now
perl -i -pe 's/^halt-height =.*$/halt-height = 8861815/' ~/.secretd/config/app.toml

# Restrat your v1.9.1 node
sudo systemctl restart secret-node

Part 4:

# Stop your v1.9.1 node
sudo systemctl stop secret-node

# Remove halt-height
perl -i -pe 's/^halt-height =.*$/halt-height = 0/' ~/.secretd/config/app.toml

# Figure out currently used db backend
DB_BACKEND=$(awk -F \" '/^db_backend =/{print $2}' ~/.secretd/config/config.toml)

# Get the v1.9.2 binaries
wget "https://github.com/scrtlabs/SecretNetwork/releases/download/v1.9.2/secretnetwork_1.9.2_mainnet_${DB_BACKEND}_amd64.deb"

# Verify the v1.9.2 binaries
echo '3c62539e1e5764bc3d5c6929d63627586f5a062afebb34cc9256bf19c5022364 secretnetwork_1.9.2_mainnet_goleveldb_amd64.deb

    grep "$DB_BACKEND" |
    sha256sum --check

# Install the v1.9.2 binaries
sudo apt install -y "./secretnetwork_1.9.2_mainnet_${DB_BACKEND}_amd64.deb"

# re-apply any systemd unit file customizations

# Restart the node
sudo systemctl restart secret-node

Note: After 1.9.2 we might apphash - this is because there might be validators that are still on 1.9.1 and have not set their halt height nor upgraded. If this happens we'll use quicksyncs to get a majority back (similar to the 1.3.0/1.3.1 halt a while back)
