Move-spuser doesn't replace user

Hi,

In sharepoint 2013 i need to replace a user by an other.
For this i use:

   

Move-SPUser -Identity "DOMAIN\JaneDoe" -NewAlias "Domain\JaneSmith" -IgnoreSID

I give permission on a site to JaneDoe puting him in a group.
After executing the command the user is remove from the group so he doesn't have anymore access but new user doesn't have access in his place!
If i get the permission again to JaneDoe his name is now JaneSmith


Could you give me a sample to replace a user by an other like stsadm -o migrateuser in SP2007
