Aug 9, 2016 7:11 PM in response to pkBrooklynby Limnos,Upgrades are available through the Software Update application. I would never ever want it to be a fully automated service because you want to make sure old software works and also that you have a solid backup before upgrading OS.
From Lion and your two options are Mountain Lion which is itself somewhat old, or El Capitan. If you decide on El Capitan make sure you have at least 4 GB of RAM and preferably 8 GB or more.

Aug 10, 2016 7:36 AM in response to pkBrooklynby Eric Root,One option is to create a new partition (~30- 50 GB), install the new OS, and ‘test drive’ it. If you like/don’t like it it, you can then remove the partition. Do a backup before you do anything. By doing this, if you don’t like it you won’t have to go though the revert process.
Check to make sure your applications are compatible.
Applications Compatibility (2)
El Capitan 10.11 Compatibility information
Also check to make sure there is a compatible driver for your printer.
Open Disk Utility, select your hard drive (step 1), then the Partition tab (step 2), and select the partition. Using the /// at the bottom move it up (step 3) until the size box decrease by about 50 GB. Select the newly created space and hit the + button (step 4). Name it something and select Mac OS Extended (Journaled) as the format (step 5). Then hit the Apply button(step 6). Download the installer from the App Store and when it starts, point it at the new partition. You might want to make a copy of the installer outside the Applications folder to avoid having to re-download it in the future. Once installed, restart with the option/alt key held down, select the new partition and reboot. Test away.

Aug 10, 2016 7:39 AM in response to pkBrooklynby macjack,Generally speaking, you should always upgrade to the latest possible system that you meet the specs for, as long as you have no “must have” apps that do not meet the specs. Upgrades and updates contain important security improvements plus additional features.

Before upgrading:
1. Backup. Anything can happen at any time,, so you should always keep a good backup. Make a bootable clone SuperDuper! or CarbonCopy Cloner or use TimeMachine.
2. If you have issues on your present system don't compound them by installing over them. Solve them first then upgrade.
3 Check HDD for free space. At least 8.8GB of available storage. Preferably much more.
4. Check your applications for compatibility here…http://roaringapps.com/apps.
5. Disconnect all peripherals, including USB hubs.
6. After downloading the installer, it will be in /Applications folder. Duplicate it and then drag the copy it to another locations like Downloads, if you want to save the installer.
7. Be patient, the download takes a long time and the install may look like it has died at times. Ignore it.
