+### Sentinel Migrations
+
+This contains important information regarding migrations.
+
+### Migration  Errors
+
+NB these migrations should only been run on MEDIDEV
+
+This is an important step, the current DB_USER on mediuk is not as powerful as
+a user with QSECOFR, migrations will fail with a resource 904 error, to overcome this
+change the active env file DB_USERNAME and DB_PASSWORD and re-run the migration.
+
+When running migrations on production always for this with care
+
+To run a migration
+
+```
+php artisan module:migrate Settings
+
+```
+
+to revert the migration
+
+```
+php artisan module:migrate-rollback Settings
+
+```
+
+### Writing Migrations
+
+In line with general Laravel Migration creation and Taylor Ortwel we do not create a down action to prevent tables
+being erased in error. Also we should check if a table exists and example ois below.
+
+```
+ /**
+     * Run the migrations.
+     */
+    public function up(): void
+    {
+        if (!Schema::hasTable(Priority::TABLE)) {
+            Schema::create(Priority::TABLE, function (Blueprint $table) {
+                $table->id();
+                $table->integer('is_default')->default(0);
+                $table->integer('is_protected')->default(0);
+                $table->integer('sort_order')->default(0);
+                $table->string('title')->nullable();
+                $table->string('slug')->nullable();
+                $table->text('description')->nullable();
+                $table->char('uuid', 36)->nullable();
+                $table->timestamp('deleted_at')->nullable();
+                $table->timestamps();
+            });
+        }
+    }
+
+    /**
+     * Reverse the migrations.
+     */
+    public function down(): void
+    {
+    }
+
+```
+
+One should never run migrations on production, any tables are to be created using IBM Utilities.
+*** and Never run the commands php artisan migrate, php artisan migrate-rollback or php artisan db:wipe.
