Bigip.conf manual reconfiguration issue

Just had to do something very similar to move from v9 to v11 with the change from IP address to name as the key. Used pycontrol to get the data out of v9 and reformatted it into a set of .tcl files. Deleted all the pools and nodes on v11 and ran a 'tmsh load sys config file (filename) merge. Yes, it was painful to write as I had to do it for everything to move the whole box to v11 (nodes, monitors, virtauls, selfIP's etc. etc.) but can build the whole config onto the viprion in about 10 mins.
