+# How to test the v1.15 upgrade with LocalSecret
+
+__NOTE__: Always work in docs/upgrades/1.15 directory
+
+## Step 1
+
+Start a v1.14.0 chain.
+
+```bash
+docker compose -f docker-compose-115.yml up -d
+```
+We use modified node_init.sh script to start a regular node.
+Let's copy this script over into the node container
+```bash
+ docker cp node_init.sh node:/root/
+```
+
+(For convenience) Open a new terminal window:
+
+```bash
+docker exec -it bootstrap bash
+```
+
+, and start a bootstrap instance:
+```bash
+./bootstrap_init.sh
+```
+
+__Note__: If for whatever reason, bootstrap_init.sh fails to start reporting an illigal instraction,
+most likely cause is /tmp/secretd left from the previous run. Try to remove and recreate this directory
+if the script fails to run, restart the compose.
+
+Open yet another terminal window where you will start a regular node:
+
+```bash
+docker exec -it node bash
+```
+
+To start a node instance
+```bash
+chmod 0777 node_init.sh
+./node_init.sh
+```
+
+## Step 2 (Test basic contract)
+
+Copy a contract to node container:
+```bash
+docker cp ./contract.wasm node:/root/
+```
+
+Shell into the node container:
+```bash
+docker exec -it node bash
+```
+
+Store, instantiate, and execute the contract:
+```bash
+secretd config node http://0.0.0.0:26657
+secretd tx compute store contract.wasm --from a --gas 5000000 -y
+sleep 5
+INIT='{"counter":{"counter":10, "expires":100000}}'
+secretd tx compute instantiate 1 "$INIT" --from a --label "c" -y
+sleep 5
+ADDR=`secretd q compute list-contract-by-code 1 | jq -r '.[0].contract_address'`
+
+secretd tx compute execute $ADDR '{"increment":{"addition": 13}}' --from a -y
+sleep 5
+secretd query compute query $ADDR '{"get": {}}'
+```
+
+Expected result should be:
+```json
+{"get":{"count":23}}
+```
+
+## Step 3
+
+Propose a software upgrade on the v1.14 chain:
+We request an upgrade to take place at +30blocks (@10block/min)
+
+Let's capture the block height:
+```bash
+UPGRADE_BLOCK="$(docker exec node bash -c 'secretd status | jq "(.SyncInfo.latest_block_height | tonumber) + 30"')"
+```
+
+Let's create a proposal and capture its ID:
+```bash
+# Propose upgrade
+PROPOSAL_ID="$(docker exec node bash -c "secretd tx gov submit-proposal software-upgrade v1.15 --upgrade-height $UPGRADE_BLOCK --title blabla --description yolo --deposit 100000000uscrt --from a -y -b block | jq '.logs[0].events[] | select(.type == \"submit_proposal\") | .attributes[] | select(.key == \"proposal_id\") | .value | tonumber'")"
+```
+
+Let's vote for the proposal
+```bash
+# Vote yes (voting period is 90 seconds)
+docker exec node bash -c "secretd tx gov vote ${PROPOSAL_ID} yes --from a -y -b block"
+```
+
+Optionally, you can check the proposal ID and the upgrade block height:
+```bash
+echo "PROPOSAL_ID   = ${PROPOSAL_ID}"
+echo "UPGRADE_BLOCK = ${UPGRADE_BLOCK}"
+```
+
+## Step 4
+
+Perform the upgrade:
+At the upgrade block height you will see `ERR CONSENSUS FAILURE!!! err="UPGRADE \"v1.15\" NEEDED at height` for both containers: bootstrap and node.
+
+At this point, the chain is waiting for the upgrade to be performed
+
+__Special note__: If you run Ubuntu 22.04 or higher, you should consider building a localsecret target, which will produce a docker image for your active branch. We assume that you are on branch with tag v1.15.0 or cosmos-sdk-0.50.x-merged as of this writing.
+
+Option A: Either build locally, if you are on Ubuntu 20.04
+```bash
+FEATURES="light-client-validation,random" SGX_MODE=SW make build-linux
+```
+Option B: build a docker image if you are on Ubuntu 22.04 or higher
+```bash
+make localsecret
+```
+
+After the build is done, assemble the binary artefacts.
+You will need the following binaries:
+* secretd
+* librust_cosmwasm_enclave.signed.so
+* libgo_cosmwasm.so
+* librandom_api.so
+* tendermint_enclave.signed.so
+
+If you chose option B, you can access the binaries in the container and copy them to a host dir,
+e.g. SecretNetwork/docs/upgrades/1.15/bin by running commands:
+```bash
+docker exec secret-0.50.x:/usr/bin/secretd ./bin
+docker exec secret-0.50.x:/usr/lib/librust_cosmwasm_enclave.signed.so ./bin
+docker exec secret-0.50.x:/usr/lib/libgo_cosmwasm.so ./bin
+docker exec secret-0.50.x:/usr/lib/librandom_api.so ./bin
+docker exec secret-0.50.x:/usr/lib/tendermint_enclave.signed.so ./bin
+
+```
+
+```bash
+# Copy binaries from host to current v1.8 chain
+
+docker exec bootstrap bash -c 'rm -rf /tmp/upgrade-bin && mkdir -p /tmp/upgrade-bin'
+docker exec node bash -c 'rm -rf /tmp/upgrade-bin && mkdir -p /tmp/upgrade-bin'
+# update bootstrap
+docker cp ./bin/secretd                               bootstrap:/tmp/upgrade-bin
+docker cp ./bin/librust_cosmwasm_enclave.signed.so    bootstrap:/tmp/upgrade-bin
+docker cp ./bin/libgo_cosmwasm.so                     bootstrap:/tmp/upgrade-bin
+# update node
+docker cp ./bin/secretd                               node:/tmp/upgrade-bin
+docker cp ./bin/librust_cosmwasm_enclave.signed.so    node:/tmp/upgrade-bin
+docker cp ./bin/libgo_cosmwasm.so                     node:/tmp/upgrade-bin
+docker cp ./bin/librandom_api.so                      node:/tmp/upgrade-bin
+docker cp ./bin/tendermint_enclave.signed.so          node:/tmp/upgrade-bin
+# stop node's secretd
+docker exec node bash -c 'pkill -9 secretd'
+# copy over updated binaries
+docker exec bootstrap bash -c 'cp /tmp/upgrade-bin/librust_cosmwasm_enclave.signed.so /usr/lib/'
+docker exec bootstrap bash -c 'cp /tmp/upgrade-bin/libgo_cosmwasm.so /usr/lib/'
+docker exec node bash -c 'cp /tmp/upgrade-bin/secretd /usr/bin/'
+docker exec node bash -c 'cp /tmp/upgrade-bin/librust_cosmwasm_enclave.signed.so /usr/lib/'
+docker exec node bash -c 'cp /tmp/upgrade-bin/libgo_cosmwasm.so /usr/lib/'
+
+# prepare a tmp dir to store validator's private key
+rm -rf /tmp/upgrade-bin && mkdir -p /tmp/upgrade-bin
+docker cp bootstrap:/root/.secretd/config/priv_validator_key.json /tmp/upgrade-bin/.
+docker cp /tmp/upgrade-bin/priv_validator_key.json node:/root/.secretd/config/priv_validator_key.json
+```
+
+Restart node:
+```bash
+source /opt/sgxsdk/environment && RUST_BACKTRACE=1 LOG_LEVEL="trace" secretd start --rpc.laddr tcp://0.0.0.0:26657
+```
+
+The log file will print out `INF applying upgrade "v1.15" at height` 
+
+If the upgrade process was successful, the blockchain will resume generating new blocks after the height at which the upgrade was requested.
+
+Chck that the previously deployed contract is still present
+Query the value of the counter:
+```bash
+secretd query compute query $ADDR '{"get": {}}'
+```
+Expected result should be:
+```json
+{"get":{"count":23}}
+```
