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.
