Q: What should I do if I got a new ipod touch and want to transfer my old data to the new one, but don't want to keep the same apple ID

Transfer content from an iPhone, iPad, or iPod touch to a new device

Then change the ID:

The ID is used in the following locations and you  have to change them.

Settings>Messages>Send and Receive

Settings>FaceTime

Settings>GameCenter

Settings>iCloud

and Settings>iTunes and App store

You  have to sign out of ID (for iCloud you delete the iCloud account from the iPod) and sign in with other ID.

Note when you delete the iCloud account select the opting to retain the data (e.g., contact, Calendar)

Also note:

- Apps are locked to the account that purchased them.

- To update apps you have to sign into the account that purchased the apps. If you have apps that need updating purchased from more than one account you have to update them one at a time until the remaining apps were purchased from one account.
