Tool to migrate LevelDB files to RocksDB files

[Ran Silberman]

Hello,
In Fortscale we use Samza 0.7 and want to migrate to 0.9.1

We want to move our KV DB from LevelDB to RocksDB.

Is there a simple utility to run a migration at our customers installation
without losing the data in the database?

Thank you,
Ran
