+Therefore, migrating all databases to `block` format is recommended to ensure optimal performance. +
+The `block` format supports token names (including node labels, property keys, and relationship type names) of any length up to the GQL identifier max length of 16,383 characters.
+Thus, token names must adhere to this length limit when migrating from `aligned` to `block` format.
+
+`standard` and `high_limit` formats are deprecated in 5.23 and will be removed in a future release.
