+# Migrating from WoltLab Suite 6.0 - Templates
+
+### Shared Templates
+
+Shared templates, applicable both in the frontend and the backend, are now standardized to begin with the
+prefix `shared_`.
+This naming convention enhances clarity and organization within the template system. All templates intended for shared
+use must adhere to this naming convention.
+
+It is important to note that these shared templates must reside within the template directory in the frontend. Whether
+they are located in the WCF template directory or in your own application's template directory.
+
+To facilitate migration, below is a table outlining the renaming of templates from their old names to their
+new `shared_` prefixed names:

+#### Migration
+
+We provide a helper script that automates the task of updating the template includes. The script will search
+for `{include file='old_template_name'}` and replace it with `{include file='shared_new_template_name'}`.
+
+The helper script is part of WoltLab Suite Core and can be found in the repository
+at `extra/migrate-shared-template.php`. The script must be executed from CLI and requires PHP 8.1.
+
+```shell
+$> php extra/migrate-shared-template.php /path/to/the/target/directory/
+```
+
+The script will recursively search the specified target directory for files with the `tpl` extension.
