The ldd command is fine, but the imapd command is not in your path.  Do 
you know where it is?  If it is in /usr/local/libexec, for example, the 
command would be "ldd /usr/local/libexec/imapd"

You should perform this on the old and the new server and see if the 
imapd's are linked against the same version of db.  If not, you will 
need to perform a db_dump on the old system, and then reimport the 
database on the new server.  You can use the cyrus specific utilities to 
make this easier.

This is not the database which is yielding the errors, since this is a 
skiplist DB and not a Berkeley DB.  What you should probably do is look 
at the imapd.conf file on the old and new servers, and check the release 
notes for both versions to see which of the different databases default 
to which DB backends in each.  For example, in some older versions of 
cyrus several databases defaulted to Berkeley DB, whereas in newer 
versions they default to skiplist.  A "man imapd.conf" should tell you 
the default for your version, and unless it is altered in the imapd.conf 
file that is what was used.

I know this is a little vague, but you haven't given us much to go on.
