This LLMQ will not remove the LLMQ_100_67 from testnet; however that quorum (likely) will not form and will perform no role.
See the [diff](https://github.com/dashpay/dash/pull/5225/files#diff-e70a38a3e8c2a63ca0494627301a5c7042141ad301193f78338d97cb1b300ff9R451-R469) for specific parameters of the LLMQ.
This LLMQ will become active at the height of 847000. **This will be a breaking change and a hard fork for testnet**
This LLMQ is not activated with the v19 hardfork; as such testnet will experience two hardforks. One at height 847000,
and the other to be determined by the BIP9 hard fork process.
