The solution proposed by Kirtan is very simple, but you need a root access to both servers to install the Migration Tool (on the old server) and the Zextras Suite Trial (on the new server)...
With other simpler solutions don't import everything, like tags, shares, preferences, passwords ...etc
If you need more assistance, look for Cine in the Zextras forum, he is very helpful.
My 2 cents
