===== Truncate Migration List =====

Truncating the Migration List itsself is easy. You only have to create a snapshot of the current database state (after correctly reseeding first).

<code bash>
php bin/cake.php bake migration_snapshot InitDb
</code>

 Then you should check if it did it correctly. You can delete all other migrations and run the new migration. If the schema dump is the same it worked. 

Be sure to check data update queries and redo them in the new unified migration if possible/necessary.

===== Upgrade cakephp/migration plugin 4.x to 5.x =====

Major changes include the swap from ''AbstractMigration'' to ''BaseMigration'' and the same with Seeds.

Be sure to check your seeds and migrations for any outputs. The new ''BaseMigration'' or ''BaseSeed'' use ''$this->getIo->out()'' instead of ''$this->getOutput->writeln()''.

Commands have also changed entirely from

<code bash>
php bin/cake.php migrations seed
</code>
to
<code bash>
php bin/cake.php seeds run
</code>

===== Namespace Separators in DokuWiki =====

The default Namespace Separator in DokuWiki seems to be '':'' which I personally find a bit confusing. Luckily there is a configuration to allow ''/'' to be used as a Namespace Separator which makes more sense.
