This document contains instructions for migrating to various storage versions.

0.1 -> 0.2

v0.2 fixes a bug in MYSQL, Postgres and Arangodb in which inserting non-UTF8 characters would trigger a panic due to the values being saved in a TEXT column instead of a BYTEA/BLOB column. Migration instructions (note you may need to adjust the table names if you have supplied a custom config to the storage):

Postgres

ALTER TABLE fiber_storage
ALTER COLUMN v TYPE BYTEA USING v::bytea;

MYSQL

ALTER TABLE fiber_storage MODIFY COLUMN v BLOB;

Arangodb

No migration other then updating the library is necessary.
