Thanks :) The migration manager was not installed by default, i had to go to Updates and Upgrades and install it.
I will migrate first to a Local virtualbox VM and then to my new server...
[edit]
It turns out that i have Plesk version 11.0.9 and the migration manager doesn't work with this...
How to achieve this ? I need to transfer all of my domains to a new server is there an easy solution to avoid manually backing up all the files, databases create new subscriptions,domains etc Also i will have to perform the same task for a local development machine which has already plesk 12...
