How to best Create Big-IP lab on VE from Physical production configuration to test upgrade?

I had done the migration from HW to VE for release upgrade tests too and the option "tmsh load sys ucs <filename> platform-migrate" alone isn't sufficient.

At the end I done a mix.

1. Export UCS "tmsh load sys ucs <filename> platform-migrate" from HW
2. config base options like mgmt ip-address etc. manual at the VE
3. Extact exported UCS file
4. Import SCF config files from the extracted UCS file with "load /sys config merge file <filename> verify"
5. Delete verify errors manual from the SCF files

This was a lot manual work.

I would be also interested in a more effective way of migration.
