But If you don’t switch your library to YouTube Music soon, you might lose out access to all of your music library, recommendations, purchased music, and personal uploads when Google Play Music eventually does get shut down.
For now, users will have access to both services, giving them time to move their music over and get used to the YouTube Music interface. But starting at the end of August, you won’t be able to purchase, preorder, upload, or download music from Google Play Music through Music Manager. And starting in September, users in New Zealand and South Africa will no longer be able to stream from or use the Google Play Music app. In the US and other areas globally, that will happen in October.
You can transfer your library using your Android, iPhone or Web Browser.
Transfer using Android or iPhone
Step 1- Open the YouTube Music App on your phone.
Step 2- You will see a pop up to upgrade to premium, close that for now.
Step 3- Most of you will see a “Transfer your Play Music Library” option on your home screen. In case you don’t see it, head to settings and you will find it there. If you are still not able to find that banner then that means Google has not initiated the transfer option on your account yet.
Step 3- You might open Google Play Music, head to Settings, and find the banner to transfer to YouTube Music there. That will lead you to YouTube Music.
Step 4- Click on “Let’s go” and your transfer will begin
Step 5- Once the process begins you will get a notification letting you know about the progress.
Step 6- You will get a notification when the transfer is complete. It might take from a few minutes to some days for it to complete depending on the volume of your library.
Using web browser
This process is not much different from how you did on the phone.
