How do you migrate application silos from onfarm to another?

I have been handed the task of migrating all published apps and content from an old (and dying) single server 3.0 farm to a multi-server 4.5 farm.  By the way, all the content is in the prod environment and considered mission critical.

Upon doing some research, I found a pdf on Citrix's site called "Technical Guide to Upgrading or Migrating to Citrix Presentation Server Feature Pack 1".  On page 12, it states "When a farm migration is chosen, Web Interface can be effective in bridging the new farm and the old
farm so that the transition is seamless to users. Either of the following approaches can be considered:
" Migrate entire application silos during a single outage window."

My questions is how do you migrate the application silo?  It mentions a FarmAppUtil tool, but I don't know if this will do it.  I cannot find any other commands to do this.  This document makes it sound like I can link the two farms and migrate the apps from one to another.  Is this correct?  If so, how do I do it?  If not, is there a way to do it?  I have alomost 100 published apps on this single server that i need to move.  Some being older proprietary SW that I might have trouble finding media for.

You would create a new 4.5 Farm, install the applications on the new servers, add the 2nd Farm to your existing Web Interface site and using security groups start moving users over to the new farm.  Your users should never notice anything happened.

i.e. Say you have Office 2003 installed.  YOu should be using a security group to allow access to that app.  Say the security group is called MSOffice.  You would now create a 2nd security group called MSOffice_45 with no users at this point.  When you publish Office 2003 in the new 4.5 farm you will give the new security group, MSOffice_45, access to the app.

When you are ready to move users to the new farm you would simply remove them from the MSOffice group and add them to the MSOffice_45 group.  When they come in the next day and log in, they will still see the Office 2003 published apps but when they click on an icon it will launch from the new servers in the new farm and they will not notice anything different (except maybe better performance).

So what you're saying is there isn't a way to migrate the application, just the application settings?  I still need to install all the apps on the new farm, correct?

Yes, you still need to install the apps on the new servers in the new farm.

Wishing there was another answer, but it is what it is
