CentOS - May 2020 - External Array Data Migration

Dear All,

Below question has been puzzled me for a while, and don?t know if anyone has
experienced such puzzle:

You have an external array attached to a physical hardware. The operating system
is CentOS 5. The file system is created on top of LVM on external array &
mounted. The CentOS 5 can see the array controller, and manage all LVM
configuration, etc. There is data stored in that external array. At some point,
you want to upgrade the operating system to higher version, CentOS 7. Is there a
fast way to migrate the external array data volume to new hardware with CentOS 7
without doing machine-to-machine rsync the whole external array data volume? In
another words, can I detach external array from old hardware, and attach it to
new hardware, then re-configure LVM, so new operating system can recognize the
external array file system?

Thanks,

- Xinhuan

If only there existed a documentation project, for Linux which included LVM
