Upgrade from 1.25 to 1.31 - pre-upgrade advice requested

[spcherub]

My client's site is running 1.25 and I would like to keep up with the releases and upgrade to 1.31. I am only using the modules installed by default but would also like to start using the Jobs module.

This is a live site and the client is extremely sensitive about downtime. Is it safe for me to upgrade to 1.31 by simply using the latest files and running install with the original db information? Or are there other tweaks I need to make as well?

Thanks!

I failed to mention I do use TinyMCE

Update: I did the practice upgrade on a test site. Seems to work fine except for TinyMCE which even though is installed does not come up when editing a page (User Preferences is set to use TinyMCE) - no WYSIWYG gui comes up at all. I uninstalled and reinstalled it using Modules, but this does not fix the problem. I tried to download the latest TinyMCE (2.4.1) using Module Manager, but this resulted in a Server Error (500).

Any ideas of how to fix the TinyMCE issue?

PS: I upgraded from 1.25 to 1.31 by simply untarring the new files over the ones already in place and rerunning install. I chose not to create the tables since I already had them from the previous install. Could I have missed a step or done something wrong.

Please check your http logS to narrow the trigger of this error.
Additional information about the hosting context is welcome too.

Unfortunately my ISP does not seem to provide me with error logs - only access logs. The server environment is the usual LAMP stack - I think Apache being 2.x, MySQL 5.x, PHP 4.x and 5.x being supported.

1.2.5 has been working great without any problems and I was even able to use he Module Manager to install the Jobs module. The problem only seems to occur when I try to install the TinyMCE module (2.4.1).

This makes it very difficult to diagnose : bad upgrade, memory problem, poor module... who knows.
You should consider another hosting provider or deactivate modules.

You ran install w/o making tables, I believe part of upgrade is writing some new tables and upgrading the schema of the DB, you maybe should have run install/upgrade.php to get a better idea, it's really quite simple and is part of the path to upgrading...
