yes, but only for the import process that will read them from influxdb and save them into the grafana database (either embedded sqlite3 or external mysql, postgres).

InfluxDB is not really suitable as a general purpose data source (storing dashboards as influxdb metric series was more a temporary solution so influxdb users did not need to install elasticsearch, and influxdb dashboard storage did not support tag filtering).

With Grafana 2.0 needs to store a lot more, users, accounts, user starred dashboards & preferences. So a more general purpose database was needed.
