Storage migrations are important for keeping your database compatible with Authelia. Authelia will automatically upgrade
|
|
your schema on startup. However, if you wish to use an older version of Authelia you may be required to manually
|
|
downgrade your schema with a version of Authelia that supports your current schema.
|
|
|
|
## Schema Version to Authelia Version map
|
|
|
|
This table contains a list of schema versions and the corresponding release of Authelia that shipped with that version.
|
|
This means all Authelia versions between two schema versions use the first schema version.
|
|
|
|
For example for version pre1, it is used for all versions between it and the version 1 schema, so 4.0.0 to 4.32.2. In
|
|
this instance if you wanted to downgrade to pre1 you would need to use an Authelia binary with version 4.33.0 or higher.
