[Anny0nn]

Migrations tested with try-runtime-cli and with chopsticks

# v0.8.0 has a bug with the blocktime config
cargo install --git https://github.com/paritytech/try-runtime-cli --tag v0.7.0 --locked --force

try-runtime create-snapshot  --uri wss://invarch-rpc.dwellir.com  --pallet System OcifStaking Balances

try-runtime \
    --runtime ./invarch/target/release/wbuild/invarch-runtime/invarch_runtime.compact.compressed.wasm \
    on-runtime-upgrade  \
    snap --path ./invarch_state.snap
