Upgrading from 2.0.15 to the latest

I just started a new job and lo and behold I found they were using a VERY old version of RT, 2.0.15
Running on Mysql 3.24.57, RedHat 7.2 and Perl 5.6.1

So I started looking at upgrading to the latest.

but the docs for 3.4.5 only goes back to 3.0.x :)…

I’m considering going to 3.0.0 first and then do 3.4.5 after that.

Any major snafus I should be aware of ?
