My experience is that you are more likely to have problems in your 
existing setup because you should always try keep the kernel newer 
than the newest jail.
your new stup shoud just work.

In the one time I had problems, I fixed it by putting a copy of libc 
from the base into /lib/base/libc.so and using libmap.conf to make 
sure everyting used it.  I was an exceptional case however as the jail 
had some private changes so that doesn't really count.
