Depends. How much of special configuration went into your jail?
If you just copy the tree over, you might "inherit" configuration
setting which just don't fit the second jail (rc.conf settings,
inetd and sshd config, etc).
I made a script of the jail(8) manpage "Setting up a Jail
Directory Tree" section which gets a single parameter (the jail's
tree root) and does all the rest for me. It can even distinguish
between first time installs and updates. If there's interest I
could publish it; with some markup it could end in some doc or
could be put somewhere into /usr/share/examples/jail/ (?).
Since buildworld is done once only, compilation takes some 70
minutes. Populating / updating a jail takes seven minutes per
tree (including the mostly nop'ed repetitive "make buildworld"
runs). Plus there's the mergemaster runs in every tree.

Don't know about NIS, but I successfully ran Samba in PDC mode in
one jail while Samba in another jail used the former to auth
users.
