Skytable migration tool
Introduction
The Skytable migration tool can be used to perform migrations between database versions. The basic idea is: "read all data from the older machine and send it over to the newer one".
For migrating versions from 0.6 to 0.7, the database administrator has to launch the tool in the old data directory of the old instance and then pass the new instance host/port information. The tool will then read the data from the directory (this was possible because 0.6 used a very simple disk format than newer versions). This approach however has the advantage of not having to start the database server for the migration to happen.
How To Use
To upgrade, one needs to simply run:
# Here `<lastpath>` is the path to the last installation's data directory and
# `<host>` and `<port>` is the hostname and port for the new server instance
sky-migrate --prevdir <lastpath> --new <host>:<port>
