No.  You _must_ have a full plus subsequent TIR and diffs or cincs
to synthesize a new full, but it does not matter how the full was
generated.  (That was for clarity--I assume you meant "to keep a
traditional full around.")

I've used synthetic fulls and cincs for years, demonstrated them in
this mailing list and found the documentation to be pretty darned
clear.  IME, they always work.  

What's been missing from this discussion (apologies if I've missed
it) is detail about what setup you or the original poster have.
What release, what platform, what is the policy config, what images
and TIR are available when it doesn't work for you, what's the
bpdbjobs output (easy way to track the progress of a synth and the
components it is using)?

I've confirmed it is working properly in 6.5.3.1 Solaris:  no
natural full exists, nor is one created--just the current synthfull
+ cinc = new synthful.  Is this (your experience, and the support
case and EEB) a 6.5.4 issue?
