Upgrading wearing a blindfold
Regardless of which path you choose, however, your upgrade journey will be a lot more difficult, if you travel it with a blindfold on. You need to be able to see the obstacles in your way, and get them out of the way before you set out, so you don’t get stuck.

This, first of all, means ensuring that your clients are ready for the upgrade. If your clients are not ready for the upgrade – if they don’t have enough disk space, or their drivers or apps crash, preventing the upgrade – you won’t succeed.

And if you don’t know that your clients aren’t ready, and roll out the upgrade to them, the upgrade will fail, causing disruption for your users and an increase in demands on your service desk.

Upgrading without the blindfold
You know how that plays out. And we know how that plays out. That’s why we’ve developed a couple of tools to help you make sure your clients are ready and able for the upgrade: The CTGlobal CompatScan™ and Update Frontend™ tools are both features in our data visualization and data analysis suite Insight Analytics™.

The tools take you safely and quickly through your upgrade process down to device level:
CompatScan™ scans and detects your clients’ readiness for the upgrade – i.e. helps you spot all the rocks on the road, before you embark on the journey, and fix them so they don’t trip up the roll-out; The Update Frontend™ tool tracks the upgrade process for successful and failed upgrades; and when you’re done, you can check your compliance status.

With these tools, you can track your upgrades and see e.g. which clients:

• Lack the disk space for the upgrade (on average 18%)
• Lack memory (on average 1.5%)
• Will fail due to driver or app issues (on average 11%)
• Will fail because of precache errors (on average 5%)
• Are actually ready for the upgrade (on average 63%)

And once you’ve upgraded, you can detect which clients have successfully upgraded, and which haven’t – and why!
