Migration from 3.6 to 3.8 is a non-issue. It is easy, and not even worth
considering as a problem. It isn't any more difficult to move from 3.6
to 3.8 as it is to move from 3.6.x to 3.6.y.
We were stuck on the RPM issue for a while, but I stopped caring. I
don't trust the RPMs produced for 3.6 since they're not from Best
Practical and their quality is unknown.
The real issue is managing all the CPAN modules, not maintaining RT.
Usually updating RHEL's Perl breaks RT, but it is easy to fix if you
have a test system you perform all the upgrades on first.
There are too many features that we use in 3.8.x to make sticking to 3.6
make any sense.

Dear Boss:
I strongly recommend going with the 3.6 version of RT. The install takes a few
minutes, and it otherwise meets all the requirements of our project. Migration
of old queues is simple. There is cost savings in the near and long-term.
There is no rpm of RT3.8 that works for RHEL (32 or 64 bit) and none seem to be
forthcoming. Someday perhaps someone will put one together, but it doesn't
look like anytime soon.
I CAN do a manual install of RT3.8 using the Best Practical install scripts.
It is not terribly hard. However, the long-term costs of this are large. The
install scripts put all the binaries, configuration files, and libraries in the
wrong places for RHEL/CentOS, and working outside the package manager means
files could be clobbered at any time. On the other hand, the rpms for RT3.6
use the package manager and put all the config files in /etc, all the perl
modules in the perl modules dir, and the various tools in /usr/bin and
/usr/sbin. The non-standard install using the scripts creates recurring costs
in the future as the system is significantly more difficult to update and
harder to maintain, like by a factor of 50 (five minutes compared to 4 hours).
Additionally, the cost of migration of old content from 3.6 to 3.8 is unknown.
Again, I will install either RT3.6 or RT3.8 but I need you to understand
and acknowledge the costs of the choice.

Thanks to Gary Greene for the info about his latest centos rpm build.
