<p class="MsoNormal">According to documents, you can convert MBR to GPT without data loss [0] and you can make LUKS conversion in-place [1]. But you can't enable LVM without moving data. Also all these operations have data loss risk all time so getting backup
before disk operations is always recommended.<o:p></o:p></p>

<p class="MsoNormal">I have a computer that I use for most of my work. It runs Slackware. To make it simple, years ago, when I first installed it, I used MBR and reiserfs for the filling system. Since then, I have descovered that LUKS provides encripted partitions,
and LVM provides re-sizable ones. I have also found that they also are more in-tune with the linux electric than MBR.<br>
What I want to know is, whether there is a way to go from MBR to GPT with LUKS and LVM and keep my exsisting filling system and data intact?<o:p></o:p></p>
