Migration
Spoiler: Migration from another plugins
Start the server with LimboAuth (+ SocialAddon, if needed) on the desired SQL database.
Then you should execute the SQL statement (e.g. in PhpMySQL or in HeidiSQL)
And set the migration-hash field to the desired value in the LimboAuth config file.
JPremium:
INSERT INTO limbo.AUTH
SELECT lastNickname, LOWER(lastNickname), IF(hashedPassword IS NULL, "", IF(premiumId IS NULL, hashedPassword, "")), COALESCE(firstAddress, ""), "", (UNIX_TIMESTAMP(firstSeen) * 1000), CONCAT(SUBSTR(uniqueId, 1, 8), '-', SUBSTR(uniqueId, 9, 4), '-', SUBSTR(uniqueId, 13, 4), '-', SUBSTR(uniqueId, 17, 4), '-', SUBSTR(uniqueId, 21)), IF(premiumId IS NULL, "", CONCAT(SUBSTR(premiumId, 1, 8), '-', SUBSTR(premiumId, 9, 4), '-', SUBSTR(premiumId, 13, 4), '-', SUBSTR(premiumId, 17, 4), '-', SUBSTR(premiumId, 21)))
FROM jpremium.user_profiles WHERE lastNickname IS NOT NULL
If you've used SHA256 in JPremium, set migration-hash to AUTHME_NP; if you've used SHA512, to SHA512_DBA. If you've used BCrypt, leave this field blank.
