Migrating an OS to HCE 1.1/
Constraints
Copied.
Constraints
- Only a CentOS 7.9 OS without a GUI installed can be migrated to HCE 1.1.
- During the OS migration, RPM packages need to be uninstalled, installed, and updated. As a result, the OS may restart unexpectedly. Back up the system disk before the OS migration. For details, see Creating a Cloud Server Backup.
- There should be at least 128 MB of available space in the memory and 1 GB on the system disk.
