Encrypted Disk (LUKS): Upgrading from RHEL 8 to RHEL 9 Problem

Posted on

Known limitations - Notable known limitations of Leapp currently include:
- Encryption of the whole disk or a partition, or file-system encryption currently cannot be used on a system targeted for an in-place upgrade.

Question:
1. How do I upgrade my encrypted (LUKS) RHEL 8? This a VM on a Pop!_OS using KVM used for development.
2. The other day I install RHEL 9 using encryption (LUKS) on a physical system before knowing the above limitation. And, created two RHEL 9 VMs w/encryption (LUKS). This is my production server.
3. Will this be fixed in future upgrades or should I be using disk encryption on RHEL?
