This way i will not have any problem to migrate 50GB of mailboxes 
By your experience, do you consider feasible to do that? which troubles or issues can i encounter?

I'd suggest you upgrade your current OSS version to the current release then upgrade to the same release of NE.
Take a copy of the /opt directory before each upgrade and you'll then have a back-up just in case things go wrong. Using this command:
Code:
rsync -avrlHKpogDt /opt/zimbra/ /data/backup/zimbra
should preserve the correct file permissions. Obviously if you prefer to take a copy of your VM you could do that instead.
