[Zope] zope upgrade and data copy

[jbr@FIZ-Karlsruhe.DE]

Hello,

I am running zope 2.5.0  on one server.

I have installed the new zope version 2.5.1 and would like to
copy all my data of the old zope server 2.5.0 of a subdirectory
( for example  /data1 )    to my new zope server 2.5.1.


1.) Should I copy Data.fs  even if the old server is version  2.5.0 and
    the new one is 2.5.1 ?

2.) Or is there a Product to download my directory /data1 to an external file
    system  and to reload it ?
    I am using zope page templates and python scripts in my directory. The
    download procedure should be able to process these types.

    Could I use  the product loadsite to upload to the new zope server then ?



With kind regards, Juergen Berger
