Upgrading on encrypted partitions from Squeeze to Wheezy
I have quite fresh installation with Squeeze here and
I want to upgrade it to Wheezy.
In [upgrade guide], I read:
Support for cryptoloop has been dropped from the
Linux kernel packages included in Debian 7.0. Existing
installations using cryptoloop need to be transitioned
to dm-crypt before the upgrade.
Since I was installing to crypto volumes (completely new
laptop with empty HDD) for first time, I left all installer's
choices intact. And I don't remember what it was.
I'm assuming that Squeeze might have supported (and offered
as default) the newer method. So how do I check whether my
partitions are encrypted this or other method?
And if I need to do the transfer, will this mean that I need
to re-encrypt the whole volume again? Can I avoid/postpone
