Successfully upgrading from 3.x to 4.x?

Post by Troodon » 2005/04/07 20:10:55

Hi all--

I am running CentOS 3.3 + updates (guess that's 3.4 :) and would like to upgrade to release 4. Can anyone report a successful upgrade using either the disc- or yum-based methods? Should I upgrade now or better wait for a higher release in order to avoid annoyances? Thanks.

Hmm.... apparently, nobody in this community has performed a successful upgrade. Well, that's good to know. :-)

Upgraded two servers from 3.4 to 4.0, one by YUM the other from disk. On the whole I recommend the Disk method. Several things I noted about the upgrade:

1) There are significant changes in the versions of SASL from 3.4 to 4. One of the servers was a mail server and I essentially had to reconfigure mail services from scratch after the upgrade.

2) One of the servers was a web server running post nuke and a module called photoshare that required GD support. RHEL 4 and Fedora Core 3 (and thus CentOS 4) do not install GD support out of the box. The fix was simple, install a package using YUM, but finding out what the problem was was not.

My recommendations are to use the disk method to upgrade and be prepared to reconfigure. If you have a server running something complicated to install like Open Groupware, that is working just fine, do not upgrade.
