Hello there,

I need XenApp 6 farm desing tips to co-exist with our current XenApp 4.5 farm, which has a Data Store (SQL 2005), License and PN Agent server and a Citrix Secure gateway server.
Our plan to have the both farms co-exist and slowly phase out old 4.5 farm.

All our users launch Citrix Published desktop and apps via Citrix Online Plugin or Citrix Web access.

How can I ensure that users still have ability to connect to old farm and new farm?

Also do I have to upgrade the following versions?

My secure gateway veersion is 3.o, Online plugin is 11.2, WI in secure gateway server is 5.0.1, and License server version is 11.6.

Please advise.

Thanks and Regards

Some thoughts i had recently about upgrading from 4.5 to 6.5:

Use 6.5^^ no "workaround" upgrade path from 6 -> 6.5 available.

Always use the newest License server available.

Some of the server roles like "license server" are available as "ready2run" VM's, for Vmware, Xen....

large Farms 8+ xenapp server can benefit from designing and deploying provisioning server and xen (or other VM vendor). You have
to check enterprise vs. platium versions here.

You cannot buy XenApp anymore, cause it's integrated into XenDesktop now = no more concurrent licenses available, but VERY interesting
upgrades to the "user model" available till end of year !

Check out the migration Feature on Web Interface 5.3:

Take your time to get a fell for the new version, policys are finally integrated into Active Directory and management changed quiet a bit.

As XenApp 6 (6.5= depends on 2008 R2), i recommend to to start from scratch and use the migration feature of webinterface to get users from the old farm to the new one.

Sry, the so called Virtual Appliances are only availalbe for Xen Server and "License Server" is NOT one of them.

Also the Powershell integration is one of my favorite reasons for switching to a newer version of xenapp very quickly.

Thanks for the info.
We are upgrading our XenApp 4.5 Enterprise concurrent licenses model to XenDesktop Enterprise CCU model.
But how do you ensure that the new PN Agent/WI server talks to both farms (old and new)?

Web Interface can be used to consolidate XenApp published applications, XenDesktop virtual desktops, and published content from multiple Citrix environments. In addition, Web Interface can facilitate the transition to XenApp 6.5 by hiding duplicate resources with identical names and folder locations making the transition to XenApp 6.5 as seamless as possible. To hide such items, modify the WebInterface.conf file as follows:
