BUG - ePO lost Group Users within Encryption Users
I'M currently migrating an ePO 5.1 to a new 5.9 instance. I configured Group Users 6 days ago and today while migrating a client (and discovered that pre-boot auth doesnt know the users) we found that the configured groups are gone.
I checked Audit and I only found the Events where I inititally added the groups plus the re-adding today.
Is there a known bug ? The AD groups configured for Encryption Users holds ~1000 users, could this be the cause ?
