[EXPERIMENTAL]

Some tools to migrate the characters and auth database from TrinityCore to AzerothCore.

IMPORTANT: backup your database before using this tool.

We cannot guarantee that the operation succeeds without side effects.

Instructions

In order to take benefit of the scripts we highly recomand to use Unix systems to execute the following script (Linux / Mac / Linux subsystem on windows etc)

Secure your server data

In order to avoid damaging your production server it's highly recomanded to save your data locally, and work on your data locally.

Using migration script on unix systems

Create an env file like following:

env.sh

# TrinityCore Characters DBs separated by colon symbol (:)
export CHARACTERS_DBS="characters:characters_test"

# TrinityCore Auth DB
export AUTH_DB=auth

# DB user / password
export DB_USER=trinity
export DB_PASS=trinity

# Hostname
export DB_HOSTNAME=arthas
export DB_PORT=3306

# Location of your dump files (sql) for characters DBs separated by colon symbol (:) you should use absolute path
export DUMP_CHARACTERS_FILES_PATH="/home/johndoe/dumps/characters_mysql_22_10_29_00_30.sql:/home/johndoe/dumps/characters_test_mysql_22_10_29_00_30.sql"

# Location of your dump file for auth DB
export DUMP_AUTH_FILE_PATH=~/dumps/auth_mysql_22_10_29_00_30.sql

Use it as source and execute the migration:

source env.sh
./migration.sh -a

You have several option for the migration:

• -a: restore and migrate
• -r: restore only
• -m: migrate only

Restore on windows

On Windows the restore have to be done manually after that, you have to execute the migration scripts on each DB manually.

File 1_xxx.sql to 5_xxx.sql needs to be executed in numeral order on characters DBs. 6.xxx and 7.xxx have to be executed on auth DB.

Check data integrity

To check the data integrity I highly recomand to create an AzerothCore server with his own dbs:

Ex in my case:

• characters: DB for TrinityCore characters data to migrate
• auth: DB for TrinityCore auth data to migrate
• acore_characters: Clean AzerothCore characters table
• acore_auth: Clean AzerothCore auth table

The following queries will help you to compare the DBs of a same kind:

Check what is missing in your migrated auth db

-- AUTH => columns and table IN AzerothCore and missing in TrinityCore
SELECT col_az.TABLE_NAME, col_az.COLUMN_NAME, col_tc.TABLE_NAME, col_tc.COLUMN_NAME
FROM information_schema.columns col_az
LEFT JOIN information_schema.columns col_tc on col_az.TABLE_NAME = col_tc.TABLE_NAME and col_az.COLUMN_NAME = col_tc.COLUMN_NAME
WHERE col_az.table_schema = 'acore_auth'
AND col_az.table_name = 'auth' AND col_tc.COLUMN_NAME is null;

If this query returns results it means that some table or columns are missing in your auth table. You can use git log -S [my table name] to find when this table have been created / modified.

Check what you should remove in your migrated auth db

-- AUTH => columns and table IN TrinityCore not in AzerothCore
select col_tc.TABLE_NAME, col_tc.COLUMN_NAME FROM information_schema.columns col_tc
LEFT JOIN information_schema.columns col_az on
    col_az.TABLE_NAME = col_tc.TABLE_NAME and
    col_az.COLUMN_NAME = col_tc.COLUMN_NAME and
    col_az.TABLE_SCHEMA = 'acore_auth'
WHERE col_tc.TABLE_SCHEMA = 'auth' and col_az.COLUMN_NAME is null;

The columns / table returned in this query have to be removed in your migrated db.

Check what is missing in your migrated characters db

-- AUTH => columns and table IN AzerothCore and missing in TrinityCore
SELECT col_az.TABLE_NAME, col_az.COLUMN_NAME, col_tc.TABLE_NAME, col_tc.COLUMN_NAME
FROM information_schema.columns col_az
LEFT JOIN information_schema.columns col_tc on col_az.TABLE_NAME = col_tc.TABLE_NAME and col_az.COLUMN_NAME = col_tc.COLUMN_NAME
WHERE col_az.table_schema = 'acore_characters'
AND col_az.table_name = 'characters' AND col_tc.COLUMN_NAME is null;

Check what you should remove in your migrated characters db

-- AUTH => columns and table IN TrinityCore not in AzerothCore
select col_tc.TABLE_NAME, col_tc.COLUMN_NAME FROM information_schema.columns col_tc
LEFT JOIN information_schema.columns col_az on
    col_az.TABLE_NAME = col_tc.TABLE_NAME and
    col_az.COLUMN_NAME = col_tc.COLUMN_NAME and
    col_az.TABLE_SCHEMA = 'acore_characters'
WHERE col_tc.TABLE_SCHEMA = 'characters' and col_az.COLUMN_NAME is null;

The columns / table returned in this query have to be removed in your migrated db. The current script dosn't remove migration tables those which starts with __

I hope that everything goes well, good fortune my friend.
