If you are moving to the CC version of Photoshop one of the first steps you may want to take is to move your presets from an older version. Depending on how many presets or changes to the default presets are part of your workflow this can be a bit of a project. Fortunately, there is an easy way. Under the Edit menu is an option labeled Presets and in the fly out is the Migrate option. When you choose this the existing older version will be found and you will be asked if you wish to migrate the presets from there. Pretty simple.

If you are moving presets from an older version into CS6 you will find information here for similar options.
This can save you a lot of work if you have brush presets, actions, workspace, or a variety of other presets including gradients, tool presets and much more. I recommend visiting the Preferences settings on occasion to make sure you are familiar with what you have decided to modify to your liking. The preferences can get corrupted over time and reviewing them and resetting them can often resolve minor operating issues.
