I have successfully used the procedure you describe several times to
convert to raid but never an encrypted partition
When you say "2. Copy the data over." what am I copying
Normally I would
cd old_filesystem; tar cf - . |(cd new_filesystem; tar xf -)
But that would just copy unencrypted data
Would you explain a bit more

While it is possible to do something like this in-place,
any mistake can permanentely destroy all your data. So an
absolute requirement is a complete backup (see FAQ for tips for
secure backup).
Now, swap is usually not put on RAID, so you can just let
it be as it is.
For the others, encryption is usually placed on top of
RAID, so here is what you can do:
1. Make degraded RAID1 partitions on the new drive
(put in "missing" for the missing partitions.
2. Copy the data over.
3. Reboot using the new RAID devices for boot/root
4. Sync the old partitions into the RAID devices.
Notes:
- You need to make the new partitions exactly (!) the
same size as the old ones aor smaller. Or you
need to repartition the old drive between steps
3. and 4. accordingly
- I recomend using partition type 0xfb end kernel-level
autodetection. For this to work, you have to use
MD superblock version 0.90.

I have a setup with 1 drive
The root, swap, and data partitions are encrypted
I want to add a second drive and convert all partitions to raid 1 encrypted
Can I do this conversion safely or do I need to start from scratch
If so I would appreciate a bit of procedure guidance
I have
Debian 6.0.5
kernel 3.4.4
cryptsetup 1.4.1
Thanks
Richard
