bor 2.0.1 with leveldb

[mcf-rocks]

bor 2.0.1 fails to start, previous worked good. Error is:

db.engine choice was pebble but found pre-existing leveldb database in specified data directory

am running with --db.engine=leveldb

Hey @mcf-rocks, can you share the config file or the command you use to start Bor? Also, if the data-dir is already populated with a different db and you want to change it, you'll need to sync again using snapshots for the pebbled. Pebbledb is now the default db engine choice.
