migrate phones from cucm 7.13 to 10.0

We just migrated from cucm 7.13 to 10.0, the cucm 7.13 was in mixed mode security.  Most phone migrated after we deleted the ctl file but the 7925 and the 7960 refuse to register to the new version.  Any ideas why?

Yes I tried factory resetting

Yes I tried factory resetting both the 7925 and 7960 and it didn't work. Both keep giving me a tftp server unauthorized error.  Even though the new cluster is set to non secure mode.
