Hi,
please try this.
1.) assign the LTM-VE the same hostname as the old one
2.) create an archive file on 10.1 (the one which hostname you used in step 1.)
3.) add at least as many interfaces to the LTM-VE as have been used on your active boxes. You will need this, as there are references to interface names in the config file, like 1.8. WARNING: If you use any interfaces named 2.1. I'm pretty sure that this will not work with LTM-VE. In that case you'll have to modify the config file (bigip_base.conf and/or bigip_system.conf) manually before step 5.)
4.) Save the license file of 11.0 (/config/bigip.license)
5.) import the archive file on 11.0 and activate it. WARNING: Do not connect the LTM-VE to the same network as the production units, as it will have the same IP addresses after config restore!!!
6.) If necessary, restore the license file
That should work.
