Joe, I'm pretty sure that unfortunately CF5 was unique in not
having any updater or even cumulative hotfix. There was a 4.01, a
4.51, a 6.1, a 7.01/7.02 and even an 8.01, but never any
5.anything. (And sadly it appears they went back and edited the
pages on hotfixes, including the CF5 ones, to make reference to
possible updaters, which may have led you to ask this question.)
And it doesn't appear there was even any cumulative hotfix
(CHF), a concept that started only in 7.02 if I recall correctly.
That would be just as good a solution for you, but again no cigar
it seems.
It seems you may have no choice but to install the HFs. It
would be nice if you could perhaps only install those hotfixes that
you had had previously on the other server, back in CF5 there was
not any organized tracking of hotfixes (as there is in at least CF7
and 8, where the CF admin has an interface for applying hotfixes
and also shows you what hotfixes you have applied).
Not encouraging, but hopefully helpful to understand the
dilemma.
