Issue: While executing the SharePoint Migrateuser staadm command,
Stsadm –o migrateuser –oldlogin -newlogin
We run in to error: New user account does not have a valid SID history.
Resolution: Use the –ignoresidhistory switch at the end of the stsadm command to overwrite the SID history forcibly.
Stsadm –o migrateuser –oldlogin -newlogin
-ignoresidhistory
Some more reference which talk about the other resolutions:
