Pretty much, but don't start ZEO until after step 4.  Also, make sure 
your ZEO connection is secure -- if both machines aren't on the same 
well-firewalled network use a VPN, stunnel, or similar.

Always always ALWAYS make sure that ZEO is stopped before trying to 
restore/replace the Data.fs.  This isn't special to ZEO (you should do 
the same with a standalone Zope) but it's very easy to shut down your 
Zope and forget that the ZEO server is still running.
