ext3

My embedded Linux device have 2 partitions:

small root partition containing OS.
big data partition which uses ext3

I want to encrypt the data partition by using encrypted file system. I don't want loose any data of the partition.

Size of the root partition is too small to hold all data of the data partition. It is not possible to use any external data storage.

Is there any tools that can convert filesystem of the data partition from ext3 to encrypted fs without copying all files to other place?
