Migration of configuration from Physical F5 to a VE F5.

This would be how I would do it:

Export the SSL certificates from the physical and import them to the virtual ensuring you keep the same names - otherwise the configuration import will fail

Build the bigip_base.conf file - basically configure the VLANS, IP addresses etc on the new virtual platform.

Copy the bigip.conf file to the new VE

merge the config: 'tmsh load /sys config file ' - work through any errors try again. You can always try 'verify' the load for errors before doing it properly.
