migration from FreeBSD 4.4 to Debian 2.2r4

[Patrick Hsieh <pahud@pahud.net>]

Hello list,

My company has a plan to migrate a FreeBSD 4.4 to Debian 2.2r4.
A couple of minutes of downtime is acceptable, but my core problem is:

How can I transfer the account/password from FreeBSD to Debian?
I may be wrong, but I remember FreeBSD uses MD5 passwd encryption while
Debian default does not. In this case, how can I migrate the
account/password from FreeBSD to Linux? Is there any thing I should keep
in mind?

Thanks.
