Hi Gerald,
I agree with Bob that upgrading version by version should be the safest
(though quite tedious) way.

However, it might be worth thinking through what data is actually on this
server and perhaps consider alternative ways of bringing the data (and
metadata) over to a 2.16 instance, either through exports or directly in
the database.

Probably you are quite familiar with the data (how much, what kind)?
Maintenance -> Data Statistics should give you an oveview of the amounts of
data and metadata.
