how to change from STABLE to RELEASE?

[Antonio Olivares]

Dear folks,

I am happily running FreeBSD 9.0-STABLE on one of my machines, but I
want to move to FreeBSD-RELEASE and use
# freebsd-update upgrade -r 9.1-RELEASE
but it does not find a valid repository.  How can I solve this issue
to move to newer RELEASE and avoid staying on STABLE because I will
have to compile/build world and it takes a good while to build and
then may have to rebuild all the ports.

Thanks in advance for suggestions/advice and words of caution.

Best Regards,



Antonio
