# Review client-side upgrade

The Client-side tvOS SDK has changed very little with the v4 release. The
primary change is the addition of `IMAAdDisplayContainer`, as seen in the iOS
SDK.

This guide walks through the process required to upgrade an existing v3
implementation to the new v4 SDK.

## Change the module name

To match the iOS SDK, we've changed the module name from
`ClientSideInteractiveMediaAds` to `GoogleInteractiveMediaAds`, so you should
make the following changes.

| Changes ||
|---|---|
| Old | ``` #import <ClientSideInteractiveMediaAds/ClientSideInteractiveMediaAds.h> ``` ``` @import ClientSideInteractiveMediaAds; ``` |
| New | ``` #import <GoogleInteractiveMediaAds/GoogleInteractiveMediaAds.h> ``` ``` @import GoogleInteractiveMediaAds; ``` |

## Create the new ad container

| Create and pass in an IMAAdDisplayContainer ||
|---|---|
| Old | ``` IMAAdsRequest *adsRequest = [[IMAAdsRequest alloc] initWithAdTagUrl:kAdTagUrlString adDisplayContainer:self.videoView contentPlayhead:self.contentPlayhead userContext:userContext]; ``` |
| New | ``` self.adDisplayContainer = [[IMAAdDisplayContainer alloc] initWithAdContainer:self.videoView]; IMAAdsRequest *adsRequest = [[IMAAdsRequest alloc] initWithAdTagUrl:kAdTagUrlString adDisplayContainer:self.adDisplayContainer contentPlayhead:self.contentPlayhead userContext:userContext]; ``` |
