Upgrading RT installed from distro packages

RT Users
1

Hello,

I’ve installed RT in a Ubuntu server version 10.04 using Debian
packages (apt-get). So the version of RT I’m running (that was
packaged) is 3.8.7. I want to upgrade RT to the latest and greatest
4.0.x.

Will using instructions under README and docs/Upgrading-3.8 get RT
upgraded for me? Or should I install RT from source on a fresh server
then export/import database and configuration data from my old 3.8.7
to the new 4.0.x installation?

Thanks in advance for the advise.

I’m not sure how Ubuntu layouts RT’s files in the system, but probably it
uses perl’s library paths for RT libs and this for sure would conflict
with RT 4.0.
And they should be isolated from each other, especially libs. In this case it’s
much harder to install RT4.0 and RT 3.8 on the same system and point them
to different DBs, so you can test upgrade.

You have at least two options:

  1. use deb packages from newer ubuntu versions. I’m not an ubuntu user
    to estimate effort here. However, in this case you can quickly
    recover DB from backup and swap back packages.

  2. use another server to perform test upgrade and swap servers.

Thanks in advance for the advise.

No, they don’t use the default library paths.

And they should be isolated from each other, especially libs. In this case it’s
much harder to install RT4.0 and RT 3.8 on the same system and point them
to different DBs, so you can test upgrade.

RT3.8 and RT4 can be installed alongside each other using the Debian
packages. The best option for RT 4 in Ubuntu using the packages is to
upgrade to 11.10 where they are already available.

I believe RT3.8 is also available on 11.10.
