How to upgrade EVE Community to EVE Professional

1. Take backup content of EVE Community folders:

/opt/unetlab/addons/

/opt/unetlab/tmp/

/opt/unetlab/labs/

FileZilla or WinSCP or rsync will be fine for this task.

2. Install fresh new EVE Professional.

3. Copy contents from backup folders to the same locations of EVE Professional.

NOTE: Do not overcopy folders itself, copy just contents from source to destination folders.
