You can migrate a single XenApp 5 farm (multiple farm consolidation to a single farm is not supported).
You should be familiar with MFCOM and PowerShell.
Installing the XenApp 6 Migration Tool
Install the XenApp 6 Migration Tool on one server in the new farm. In most cases, this is the server where you installed and configured XenApp 6 to create the farm.
- Download the XenApp 6 Migration Tool from My Citrix.
- Double-click Citrix.XenApp.Migration.exe; the self-extracting executable launches an MSI that installs the module. During installation, you are prompted to set the PowerShell execution policy to unrestricted, if the current policy setting differs.
- The installer creates shortcuts in the Start menu. Clicking (launching) the shortcut opens PowerShell and loads the module. (If you do not use the shortcut, open a PowerShell console and type Import-Module Citrix.XenApp.Commands.)
When launching the XenApp 6 Migration Tool, restart the server if you receive the following error message: Import-Module: The specified module 'Citrix.XenApp.Migration' was not loaded because no valid module file was found in any module directory.
Citrix recommends performing the migration entirely from a server in the new farm. If your deployment does not allow this, see Advanced Cmdlets
