How to open migration assistant on an ipad How do I open migration assistant on an iPad-2?

I have tried in settings but can not find it.
If you still have the old iPad, make a backup via iTunes or iCloud, reset the new iPad if you have already activated it as a new iPad, and when asked, select the "Restore from backup" option.
