Citrix Presentation Server 4.0 upgrade to Xen Apps

Posted on 2009-04-21
Last Modified: 2013-11-11
I'm in the process of consolidating our Citrix environment and I'm now looking at moving our farm to XenApps. Is there a "direct" upgrade path from PS4.0 to XenApps? I've found documentation on PS4.5 but nothing really based on 4.0

    Are you going to move to XenApp 5 on Server 2003 (AKA Presentation Server 4.5 with Feature Release 1) or XenApp 5 on Server 2008?

    It'll be XenApp 5 on Server 2003

    Then it is a fairly simple migration.  

    How many servers do you have?

    What are you using for your data store?  Access, SQL, MSDE, SQL Express, Oracle, DB2

    Current position:
    4 Citrix servers -
    NTCitrix - Win 2000 - Master with SQL Database
    NTCitrix1 - Win 2000
    NTCitrix2 - Win 2003 + Uniprint
    NTCitrix3 - Win 2003
    We would like to decommission the Win 2000 servers and move the master database to one of the 2003 ones. Then to upgrade the other 2 servers to XenApps for 2003.

    The licence server is on a separate server which does not run Citrix.

    Citrix does not recommend that SQL Server be installed on a XenApp server.


    You can safely uninstall all the Citrix components from the 2 Win2000 servers IF this is a FULL SQL Server install.  If it is MSDE or SQL Express you will need to move that to another server first.

    Install XenApp 5 for Server 2003 on one of the 2003 servers, reboot and it will become the data collector.
    Install XenApp 5 for Server 2003 on the other 2003 server and reboot.
    On the Win 2000 server with SQL Server on it, I would recommend leaving it alone.
    On the other Win 200 server, wipe it by loading W2K3 and doing a quick format of the drive and then install XA5.

    Citrix does not recommend or support upgrading the OS of a server with XA installed.
    I don't like to upgrade the OS of a server with installed software on it (i.e. SQL Server).

    Oh yeah, the Citrix License Server will need to be upgraded to 11.6.1
