[CentOS] CentOS 6 P2V alternatives?

Hello all,

This week I've tested out a few ways to do a P2V on a rather ancient CentOS
6 server, in order to move it to a Hyper-V host.

So far my tests have failed rather spectacularly.
Initially I was set on doing a simple dd-routine, but was told that the
server cannot be taken off-line as it's being used daily, so had to look for
other solutions.

The disk setup is currently as follows:

Three 500 GB sata-disks, sda, sdb and sdc, are used to build a software raid
called md0. No LVM's here.

Sdd is a 120 GB drive, with partitions for boot, swap, home and /. 
No LVM's here either.

The farthest I've gotten is with the Rear solution. 

The backup goes well, but recovery for some reason fails to create initramfs
with all the installed kernels, as well as failing with an error saying it
cannot find /boot/grub, after which the recovery terminates.

Virtualizing systems like this is kinda' new to me, having it done on
Windows only, and I'm not really sure
how to proceed when it's a CentOS system in question.

The physical CentOS-server runs a few license managers and nfs-shares that
server molecular modeling software, that are rather intricately set up (I
inherited this server some fifteen years ago).

Are there any easier ways to do a P2V at all?
