+# Upgrade Guide
+
+Upgrading Dynamsoft Document Viewer from an old version to the latest version (v3.x as of now) is straightforward. You need to pay attention to the following changes:
+
+* Changes of APIs
+* Changes of [`UIConfig`](/api/interface/uiconfig.md)
+
+
+There are some code snippets that are frequently used and we will talk about the changes you have to make.
+
+## Initialization of Edit Viewer
+
+In v2.x, you can use an additional options parameter to enable the annotation icon in the default UI.
+
+```js
+const editViewer = new Dynamsoft.DDV.EditViewer({
+    container: "container",
+    uiConfig: Dynamsoft.DDV.getDefaultUiConfig("editViewer", {includeAnnotationSet: true}),
+});
+```
+
+In v3.x, the option is removed and the annotation icon is included in the default UI. So you can just initialize it with the following code:
+
+```js
+const editViewer = new Dynamsoft.DDV.EditViewer({
+    container: "container"
+});
+```
+
+## Default UI Config
+
+The default UI elements may be different across different versions. Check out [this post](/ui/default_ui.md) to learn about the default configs.
+
+You can try to unify the UI across versions by specifying the [`UIConfig`](/api/interface/uiconfig.md). But pay attention to supported [elements](/ui/default_elements.md) of different versions.
+
+## Getting the Page Data
+
+Before v3.x, [`getPageData()`](/api/interface/idocument/index.md#getpagedata) returns a promise object, which was time consuming as it required getting all the image blobs. In v3.x, it directly returns an [`IPageData`](/api/interface/ipagedata.md) object and you can retrieve image blobs with its functions.
