Seems priority would be to update the code to latest substrate version. | |

No, that's impossible. Unless you modify the consensus engine. BTW, you can use the latest version. No more unexpected epoch change in the future.

IMHO --dev is not a good choice, as he is on relaychain env. --dev will build a brand new genesis state. Which may cause some syncing issues. But if --chain could override the --dev's default chain, that's fine.

or run with --dev which will implicitly use --tmp flag to use a fresh db each time.

Just remove the data dir. If you specify the --base-dir or -d then there it is. If not, on Linux it will be ~/.local/share/<chain name>, on Mac it will be ~/Library/Application Support/<chain name>.
