[OpenAFS] Offline migration of AFS partition files (i.e. the contents of `/vicepX`)

[Ciprian Dorin Craciun]

Quick question regarding the following situation:  one of my `/vicepX`
AFS partitions is currently stored on an old disk (with JFS as
file-system) and I thus I need to move all my AFS data from that
partition to a fresh one (Ext4);  moreover during this movement
OpenAFS is not running (and I intend to upgrade the server version
also from 1.6.5 to the latest one).

Can I safely `rsync` the files from the old partition to the new one?

Is there another alternative that doesn't require actually staring OpenAFS?

(I know about `voldump`, however it requires me to execute it for each
volume, and thus I might "forget" something.  Moreover it requires
extra storage space for the resulting archive.)

Thanks,
Ciprian.
