Enabling the TDE in Database Servers.

Hello,

I am in process of implementing the TDE and I have the following questions. The requirement is Enable to TDE in Database Servers.

1.  We are planning to use the SQL Server 2014 Enterprise Edition, Is there any other SQL Server Edition Supports the TDE? Currently we are in the Development Phase so it’s not a Production Server.
2. And we are planning to enable the TDE in 2014.
3. The Requirement is Client is using the SQL Server 2012 Enterprise Edition and they are planning to enable the TDE, If I take the backup from SQL Server 2012 and Restore it on 2014 is that will work ?
4. I have basis question on the Keys, Like I explained about there is going to 2 Servers 
   • First one is with SQL Server 2012 Enterprise Edition with TDE (Which contains its own key’s)
   • Second  Server is SQL Server 2014 Enterprise Edition with TDE (Which contains its own key’s)

• Now each server has its own keys what happens when I restore 2012 backup to 2014 Server?
• Do I need to bring the Key and Certificate from 2012 to 2014 ever time? How this works. Please someone help me.

Thanks

JK
