Senior Certified Citrix Professional offering assistance for this new migration. i see possibilities by building a greenfield, setting the storefront server(s) as new point of entrance to the Citrix resources. This way we can define multiple farms (like the old XA5 and the new farm) which makes the migration a whole lot easier. In the meanwhile we can build the new environment, which uses PVS to stream the application servers.
If i have interested you with this small part of a possible migration, you can add me at skype: [login to view URL] and we'll talk further.
Regards,
Kyrian
-edit: after the PM adjusted the milestone, total project cost and time to deliver
