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. Before the migration, the system disk is automatically backed up. You can also create a server backup to manually back up the system disk.
There should be at least 128 MB of available space in the memory and 1 GB on the system disk.
