Migration options (advanced)

The main migration guide is located here. Here we document a couple of advanced options you can use if you wish to have more fine-grained control.

Export validators

The default command for exporting your slashing protection history is:

build/nimbus_beacon_node slashingdb export database.json

This will export your history in the correct format to database.json.

On success you will have a message similar to:

Exported slashing protection DB to 'database.json'
Export finished: '$HOME/.cache/nimbus/BeaconNode/validators/slashing_protection.sqlite3' into 'interchange.json'

Export from a specific validators directory

The validator directory contains your validator's setup.

build/nimbus_beacon_node slashingdb export database.json --validators-dir=path/to/validatorsdir/

Export from a specific data directory

The data directory (data-dir) contains your beacon node setup.

build/nimbus_beacon_node slashingdb export database.json --data-dir=path/to/datadir/

Partial exports

You can perform a partial export by specifying the public key of the relevant validator you wish to export.

build/nimbus_beacon_node slashingdb export database.json --validator=0xb5da853a51d935da6f3bd46934c719fcca1bbf0b493264d3d9e7c35a1023b73c703b56d598edf0239663820af36ec615

If you wish to export multiple validators, you must specify the --validator option multiple times.

Import validators

The default command for importing your validator's slashing protection history into the database is:

build/nimbus_beacon_node slashingdb import database.json

Import to a specific validators directory

The validator directory contains your validator's setup.

build/nimbus_beacon_node slashingdb import database.json --validators-dir=path/to/validatorsdir/

Import to a specific data directory

The data directory contains your beacon node's setup.

build/nimbus_beacon_node slashingdb import database.json --data-dir=path/to/datadir/
