Ruby on rails - migrate a db from SQLite to PostgresQL with taps

Question

I am migrating a database from sqlite3 to PostgresQL with taps. I am trying to start the taps server on the sqlite database as follow

$ taps server sqlite://db/development.sqlite3 user password

However I got the following message thus I believe it didn't work well. Would you understand this kind of message as follow?

You'll have to force a lower version of tilt, I'd try tilt 0.8, since that was the most recent version of tilt when sinatra 1.0 was released. Note that taps is a dead project, you should probably consider migrating to something else. You could try:

sequel -C sqlite://db/development.sqlite3 postgres://user:password@host/database
