Good morning All!

I am in the process of upgrading from CUPS version 1.1.22 to 1.3.9. Everything appears to be working fine in my test environment, but I want to make sure that I am able to backup the existing CUPS version on the live environment prior to making any changes. (I don't expect any issues, but I'd rather be safe than sorry!)

Any recommendations on how I would go about this? I've tried to find a clear cut / step by step process but have been unable to find any information.

Thanks in advance...I appreciate your input!!

You get the install package for the older version, and backup the config file for cups, in /etc/cups/cupsd.conf. If the new version fails, install the old one again, and put the config file back in place.

If you use a package system to install/update software, something like rpm and yum, then you will have to ability to switch back to an older software version. RPM install/upgrades will actually save your configuration files, and install the new one with the extension *.new.
Cups is usually not difficult in terms of upgrading, so if it works on the test environment, then you will probably have no problems on the target PC.
