• User experience issues
• Lack of visibility across silos
• Complex and/or slow issue identification
• Proactive problem solving
• Lack of representative baselines
Poll: What Are Your Biggest Migration Performance Challenges?
![Page 5: Citrix and Desktop Migration Success](https://reader037.fdocuments.in/reader037/viewer/2022102814/5496ef6eb479598c6f8b473b/html5/thumbnails/5.jpg)
Significant change underway in today’s IT environments:
• Traditional desktop to virtual desktop (including upgrade XenApp 4.5 to 6.5, 6.5 to 7.5, Windows XP to Windows 7/8)
• Physical to cloud migration, including hybrid cloud. Don’t forget software!
• Virtualization of infrastructure and app layers—some legacy apps not designed for virtualization
• Moving off Windows Server 2003 and AIX. They’re still out there!
Users expect the same or better performance after the migration as they had before the migration. And when performance
problems occur, the migration is blamed first.
Migration Trends
![Page 6: Citrix and Desktop Migration Success](https://reader037.fdocuments.in/reader037/viewer/2022102814/5496ef6eb479598c6f8b473b/html5/thumbnails/6.jpg)
• Migration increases complexity of underlying IT platforms—Dependencies discovered the hard way.
• Migration project delays due to unexpected performance and availability issues
• Migration project cost overruns due to new hardware and software demands/requirements greater than original design
• Legacy applications running on legacy infrastructure. Don’t know where to start.
• Configuration Drift: ITSM issue that leads to performance issues
Common Migration Challenges
![Page 7: Citrix and Desktop Migration Success](https://reader037.fdocuments.in/reader037/viewer/2022102814/5496ef6eb479598c6f8b473b/html5/thumbnails/7.jpg)
Where the puck’s going
![Page 8: Citrix and Desktop Migration Success](https://reader037.fdocuments.in/reader037/viewer/2022102814/5496ef6eb479598c6f8b473b/html5/thumbnails/8.jpg)
Challenges ahead
• Where does my application reside? What services/infrastructure does it depend on?
• Will my current monitoring tools work in new environments my applications/infrastructure are moving to?
• Can I get a true “single pane of glass” of performance levels from multiple monitoring tools?
• Can I maintain configuration integrity when changes are constantly made?
• Can I maintain a consistent view of end-user experience as applications and infrastructure migrate, especially with more applications being accessed by mobile devices?
• Can I foster more collaboration/cooperation between developers and operations teams (DevOps)
![Page 10: Citrix and Desktop Migration Success](https://reader037.fdocuments.in/reader037/viewer/2022102814/5496ef6eb479598c6f8b473b/html5/thumbnails/10.jpg)
Migration Considerations
Configuration
• Configuration at the hardware/OS/app layers
• Physical Virtual / 32 Bit 64 Bit
• App/OS Compatibility
• App/OS Dependencies
• Private/Public Cloud dependencies & setup
• Assessments

Migration Considerations
Performance• Performance Baselines of pre-migration environment.
• Total performance visibility into the post migrated environment
• User Experience tracking
• Identifying Bottlenecks, Peak Usage, Capacity
• Critical when it comes to migration, but often overlooked
![Page 12: Citrix and Desktop Migration Success](https://reader037.fdocuments.in/reader037/viewer/2022102814/5496ef6eb479598c6f8b473b/html5/thumbnails/12.jpg)
3 Keys to Success
Citrix & Desktop Migration
![Page 13: Citrix and Desktop Migration Success](https://reader037.fdocuments.in/reader037/viewer/2022102814/5496ef6eb479598c6f8b473b/html5/thumbnails/13.jpg)

Citrix & Desktop Migration
Performance Baselines
![Page 14: Citrix and Desktop Migration Success](https://reader037.fdocuments.in/reader037/viewer/2022102814/5496ef6eb479598c6f8b473b/html5/thumbnails/14.jpg)
Performance Baselines
• How is the user experience in the pre-upgrade environment?
• What are the current usage patterns in the pre-upgrade environment?
• What are the consumption patterns in the pre-upgrade environment?
• What are the baselines for the pre-upgrade environment for user/app/OS/infrastructure performance?
• Ability to track all of the above in the post-upgrade environment and compare
• Key to success is to get equal or better user experience without compromising other KPIs

12:00 The Citrix admin decides to reboot the server but the problem persists even after the reboot.
13:00 The problem does not appear to be specific to Citrix. The Citrix admin calls for a conference call with the other administrators .
17:00 After hours of troubleshooting, the problem is identified in the VMware tier!

Real-World Example - Revisited
06:30The helpdesk receives an automatic alert saying that access to Ctirix is slowing down. No user has been impacted yet.
6:30AM
Helpdesk
This looks odd. Let’s get to the bottom of this before users start calling …

Focus on the Root-Cause, Not Effects
Without root-cause diagnosis, you have no idea where the problem lies
With root-cause diagnosis, you have a clear idea of what to do to resolve the problem.
All the problems appear to be equally important.

The effects of the problem

The Result
06:30 The helpdesk seels an alert of a slowdown with Citrix access.
06:35The helpdesk reviews the service topology and determines that there is an issue on the VMware server. Contacts the VM administrator.
06:45The VMware administrator realizes that the backup job is impacting the user experience. Reschedules the backup job for later in the evening.

• High level goals in any of these migrations is to upgrade as much of the infrastructure as possible to avoid major architectural work every time an upgrade needs to take place.
• Current major Migration initiatives in flight today:

• Approximately 33% of Desktops still running XP
• Even if you are 80% migrated, there is considerable work to be done
• Why is it imperative that you finish the migration process?
• Security upgrades WILL end soon
• Third party software companies will cease support soon
• No ability to acquire new hardware that supports XP
• The cost for extended support from Microsoft will continue to increase over time
