Upgrade / Migration Help from version 3.8.1 to 4.2.3

Hi,

I am new to the RT lists as well as new to the administration of the RT
product. My company has used RT for many years but was maintained by
another admin.

I have been asked to upgrade our RT system from version 3.8.1 running on
CentOS 5.9 to version 4.2.3 running on CentOS 6.5. Since I am
installing a new OS on new hardware, I will be installing Apache, Perl,
mySQL, etc from the CentOS 6.5 rpm repositories.

Being completely new to the administration of RT, I was not sure which
path was most practical (or possible).

  1. Build new server with new OS and newer version of Perl, Apache,
    mySQL and latest version of RT and then try to migrate or copy over our
    customizations and databases.

-or-

  1. Build new server, OS, Perl, Apache, mySQL but copy over our current
    version (3.8.1) of RT, get it to work on the new server and then perform
    upgrades?

I wasn’t sure if one path was more reliable, practical, etc.

I am currently in the process of doing a new install just so I can
become familiar with everything before I pick a path.

Any advice would be appreciated.

Thanks,

-David

This is what we do during a Best Practical upgrade.
You import your database and follow our upgrade instructions and then
you get to play whack-a-mole with your customizations and figure out
what is already a core feature.
