 ```
 
+### Known Issues
+
+#### RHEL migrations show error messages during conversion
+
+```
+  Installing       : rocky-release-8.3-13.el8.noarch                        2/5Error unpacking rpm package rocky-release-8.3-13.el8.noarch

+error: unpacking of archive failed on file /usr/share/redhat-release: cpio: File from package already exists as a directory in system
+error: rocky-release-8.3-13.el8.noarch: install failed
+Error: Transaction failed
+```
+
+This results from conflicts in the directory structure of RHEL with that of
+RockyLinux.  migrate2rocky will detect the issue and go on to remove the
+conflicting directory and install rocky-release with the rpm command.
+
+#### Grub still shows kernel entries from previous installation
+
+This is normal.  The running kernel cannot be safely removed when migrate2rocky
+is run.  The RockyLinux kernel should come up as the default highlighed kernel
+on reboot but the other ones will remain until they are removed or replaced by
+newer kernels.  If you want you can manually remove the old kernels after reboot
+with dnf or rpm.

 ### Debugging
 
 The `migrate2rocky` script pipes everything shown on `stdout` and `stderr` to
