They will register and work, but no SSL functions will work, eg secure Extension mobility or the corporate directory.

My problem is I want to use the "Prepare Cluster for Rollback to pre-8.0" parameter, but I can't change the option 150 in the DHCP server until the next day. My question is once I set this parameter and I reset the phones they will register with an empty ITL file, but will the phones still function? If I can reset the phones to clear the existing ITL and have them work the following day I can then change the option 150 to the new cluster and then reset the existing phones and add new phones in. I know I can lab this up, but wanted to make sure there were no gotchas associated with this method.
