I did that and would not do it again for a massive upgrade: 
http://lists.freebsd.org/pipermail/freebsd-questions/2008-August/180336.html

Using freebsd-update for a (minor version) upgrade to 7.1-RC1 and after 
that using 7.1-RELEASE packages for a portupgrade will probably take 
less time overall.

See the 7.1-RC1 announcement on how to do the first part: 
http://lists.freebsd.org/pipermail/freebsd-stable/2008-December/047014.html

When it is available, you should upgrade to 7.1-RELEASE, which will take 
less time with freebsd-update from 7.1-RC1 than from 7.0-RELEASE, since 
there are less configuration file changes to be merged.

For the portupgrade, you should have in mind that portupgrade uses the 
ports tree to know what to upgrade to which version. Your ports tree is 
newer than the 7.1-RELEASE packages. Anyhow, if the newest package is 
not available but a newer one than the one installed, portupgrade 
usually works, too. Reading /usr/ports/UPDATING before is still advisable.

You might still run into problems of the nature that kde was used to be 
build against openldap23-client at the time of 7.0-RELEASE, but the 
7.1-RELEASE packages are build against openldap24-client and these two 
ports cannot coexist. With ports this is not a problem, since it can be 
build against either version. (AFAIR, this particular case will work out 
fine, but there was something else requiring manual work besides 
everything listed in UPDATING.)

Probably not for 7.0->7.1, but in some cases removing all packages and 
reinstalling all takes less time than anything else.
