Hi,
Thank you for contacting the Mobile Ads SDK support team.
Before you can display ads within your app, you'll need an Ad Manager account and activate one or more ad unit IDs. Migrating from AdMob to Ad Manager should not require significant changes to your app's source code, you may need to update your ad unit IDs and integrate the Ad Manager iOS SDK into your app replacing them with your Admob SDK. This is rewarded and banner implementations for your reference.
I hope this helps! Let me know if you have additional questions.
