Manual testing

Import a recent rolling node snapshot.

wget https://mainnet-v16.xtz-shots.io/mainnet-3384776.rolling
./octez-node snapshot import mainnet-3384776.rolling --block BLk819t5YtJFbTWnX1jofymmwH5x4xHnZ7iPTmd9mGMbvYRsNve

Patch the files for yes wallet/node.

dune exec devtools/yes_wallet/yes_wallet.exe -- create from context ~/.tezos-node in /tmp/yes-wallet --active-bakers-only
patch -p1 < scripts/yes-node.patch

Patch the node configutation such that it upgrades the protocol.

Run the following in one terminal to start the node.

./octez-node run --synchronisation-threshold 0 --connections 0 --rpc-addr localhost

Run this in another terminal to bake the block migrating to Nairobi:

./octez-client -d /tmp/yes-wallet bake for --minimal-timestamp

You should see something like this in the node logs to show Nairobi activation:
