+# Migration Guide
+
+## Migrate from `1.x.x` to latest
+
+1. Migrate `HeaderStyle`.
+   ```dart
+    // Old
+    final style = HeaderStyle(
+      headerTextStyle : TextStyle(),
+      headerMargin : EdgeInsets.zero,
+      headerPadding : EdgeInsets.zero,
+      titleAlign : TextAlign.center,
+      decoration : BoxDecoration(),
+      mainAxisAlignment : MainAxisAlignment.spaceBetween,
+      leftIcon : Icon(Icons.left),
+      rightIcon : Icon(Icons.right),
+      leftIconVisible : true,
+      rightIconVisible : true,
+      leftIconPadding : EdgeInsets.zero,
+      rightIconPadding : EdgeInsets.zero,
+    );
+   ```
+   ```dart 
+   // After Migration
+
+   // NOTE: leftIconVisible and rightIconVisible is removed in
+   // latest version. set leftIconConfig and rightIconConfig null to
+   // hide the respective icon.
+   final style = HeaderStyle(
+      headerTextStyle : TextStyle(),
+      headerMargin : EdgeInsets.zero,
+      headerPadding : EdgeInsets.zero,
+      titleAlign : TextAlign.center,
+      decoration : BoxDecoration(),
+      mainAxisAlignment : MainAxisAlignment.spaceBetween,
+
+      // Set this null to hide the left icon.
+      leftIconConfig : IconDataConfig(
+        padding: EdgeInsets.zero,
+        icon: Icon(Icons.left),
+      ),
+
+      // Set this null to hide the right icon.
+      rightIconConfig :  IconDataConfig(
+        padding: EdgeInsets.zero,
+        icon: Icon(Icons.right),
+      ),
+    );
+   ```
+2. Migrate `CalendarPageHeader` | `DayPageHeader` | `MonthPageHeader` | `WeekPageHeader`:
+   ```dart
+      // Old
+      final header = MonthPageBuilder({
+        date = DateTime.now(),
+        dateStringBuilder = (date, {secondaryDate}) => '$date',
+        backgroundColor = Constants.headerBackground,
+        iconColor = Constants.black,
+      });
+   ```
+   ```dart
+      // After Migration
+      final header = MonthPageBuilder({
+        date = DateTime.now(),
+        dateStringBuilder = (date, {secondaryDate}) => '$date',
+        headerStyle = HeaderStyle.withSameIcons(
+          decoration: BoxDecoration(
+            color: Constants.headerBackground,
+          ),       
+          iconConfig: IconDataConfig(
+            color: Constants.black,
+          ),
+        ),
+      });
+   ```
