Can you copy the state (db) of a fully up to date node (on MacOS) to a fresh node on Ubuntu, and have it be starting at the copied state?
In principle this should be possible. The format should be platform independent, although I am not guaranteeing that.
To do it
- stop the node and wait for it to fully shut down
- copy the entire
database-v4
directory to the new location - start the new node
