How do you upgrade to Citrix XenApp and which version should you upgrade to?

Upgrading to new versions of Citrix can be simple or complex - depending on where you are starting from, but very worthwhile, as the benefits of the latest versions are compelling - including better user experience, more users per server and simplified application deployment.

Centralis can help with upgrade, migration and design services, ensuring a smooth transition to the new platform and that you get all the benefits from the new software.  We can also roll-up services, licensing and support into framework agreements, spreading costs over a number of years if required.

Centralis use a simple methodology to help customers upgrade:

• Analyse your technical and business requirements
• Identify any outstanding issues
• Identify the options and costs plus our recommendations
• Plan the upgrade (including a new design if needed)
• Migrate users, applications and key settings from the existing environment
• Use best practice methodology and tools such as Harvester to minimise costs
• Deliver on time and to budget - including documentation

"The project was completed to our complete satisfaction....We were extremely impressed with the professionalism that the Centralis consultants showed throughout, the depth of knowledge they had of Citrix and its surrounding technologies, and the level of expertise they showed in executing the phases of the installation. Initial testing has gone extremely well, with very positive feedback from users" Chris Bulley, Systems Support Officer, Mid Sussex District Council
