How to migrate from RT2 to RT3.4.1?

Hi

I’ve tried to migrade an RT2 installation to a new RT 3.4.1
installation, but so far without luck.

I’ll appreciate if somebody can kick me in the right direction for
this. From what I’ve read in the mailing lists (and experienced so
far) then the steps should be like:

  1. On the RT2 machine, use rt2-to-rt3-1.23 (rt-2.0-to-dumpfile) , to
    get dumps from the existing mysql database.
  2. Moved the dumped database files to the new RT3 machine.
  3. Use the earliest version 3 of RT 3.0.12, when using
    dumpfile-to-rt-3.0 (because RT 3.4.1 code in not compatible with the
    dumpfile-to-rt-3.0 code).
    For this to work the correct version of perl and Storable must be
    present, otherwise the dumper tickets from the RT2 dump cannot be
    read.
  4. Next follow the 3.0.12 upgrade steps (as found in README/UPGRADE files).
  5. Finally install RT 3.4.1 and follow upgrade steps (as found in
    README/UPGRADE files).

Is something missing in these steps?

Best regards,
Thomas

Thomas,

I upgraded from 2.0.15 to 3.2.3 then to 3.4.1 basically doing the steps
that you
mentioned.

We’re using PostgreSQL rather than MySQL, so I suspect that your issues
may be
different to those I experienced. I had trouble with the default
database encoding
changing between the major versions of RT - this was an issue in
importing the tickets
back into the fresh 3.2.3 install. The next issue was the database
sequence numbers,
followed lastly by problems with the table schema for the custom fields
(Although this
wasn’t a show stopper until we started trying to use custom fields).

My perl modules were installed direct from CPAN with the latest versions
with no
problems. I kept the original server running along side the new one
until I was
happy with everything, so the export happened with the older libs.

Are you having specific problems that others on the list may have
experienced?

Hallo,
I’ve upgraded from 1.0.1 to 3.2.3 (with all the intermediate steps), and
all workes almost good.

The problem is that when you try to upgrade from 3.2.3 to 3.4.x, there
are big problem on the tickets (the comment are lost .!)

I also tried to install an intermediate version 3.3.x but the problem
was the same.

So maybe you could start to upgrade to the 3.2.3 version.

Anyone else had this problem (i.e. migratione from 3.2.3 to the latest ?)

Thanky you
