Grow UBI device?

Hi,
I'm looking for a clever way to migrate devices (in the field) from
JFFS2 to UBI/UBIFS. In the end result, I want to have single UBI
device (which covers the whole NAND chip) with several volumes used
with UBIFS. Unfortunately I must keep some of the existing data.
It would be nice if I could start with a UBI device that is smaller
than the NAND, so I can keep an existing MTD partition with a JFFS2
file system. After copying the data from JFFS2 to a UBIFS volume, I
would like to free and reuse the space of this JFFS2 partition.
Is there a way to "grow" the existing UBI device so that it now also
covers the rest of the NAND chip? Or is my only option to create a
second UBI device?
Thanks in advance.
Best regards,
Wolfgang Denk
