please post questions in the data protection forum ;-)
But no, Microsoft do not support upgrade of encrypted disks.
Thank you. Wrong forum? There are times I find this forum software less than intuitive when it comes to posting!
this is a group - for tech questions, use the community from the menu on the left.
I'm not really sure what groups are for ;-)
We do have a document that covers this. I am adding it just in case someone finds this topic at a later date by search.
KB60832 - Upgrading a Windows operating system with Endpoint Encryption for PC installed
The interesting bit for all is this:
Upgrading to Microsoft Windows 7
McAfee has worked with Microsoft to include a step to check for the Endpoint Encryption during an Upgrade to Windows 7. If the Windows 7 installer detects Endpoint Encryption on the system, the installation will stop and display a message that the upgrade cannot continue while Endpoint Encryption is installed. The notification will direct the user to this Knowledge Base article.
All the best.
