Hi Im looking at upgrading my Windows 2003 / Citrix Presentation Server 4 farm to XenApp 4.5. I cannot migrate to new hardware. There are 2 options: 1) Uninstall Citrix Presentation Server 4 and Install XenApp 4.5 2) Install XenApp 4.5 over the top of Citrix Presentation Server 4 Im looking at Option 1 as I feel it may be cleaner. Can anyone recommend the best way to upgrade and ensure no issues are encountered.. Which option should I go with? Thanks Ang _________________________________________________________________ If It Exists, You'll Find it on SEEK Australia's #1 job site http://clk.atdmt.com/NMN/go/157639755/direct/01/
