Hi @melissag57222326
@Kevin-Monahan is correct to avoid copying the whole preferences folder manually — moving those around yourself is likely to cause problems. To address each item you mentioned:
1. I highly recommend using the built-in migration feature: After Effects > Settings > Startup & Repair > Migrate Previous Version Preferences. This should detect your 17.x preferences and migrate them over to 24.6. It will migrate all the application preferences, workspaces, keyboard shortcuts, and any scripts installed in the preferences folder (e.g. if you installed them using File > Script > Install Script...)
2. Presets — Copy any custom .ffx files from ~/Documents/Adobe/After Effects [old version]/User Presets/ into the equivalent User Presets folder for 24.6.1. Skip the presets inside /Applications/... — those are just factory defaults and are already included in the new version.
3. Scripts — Check /Applications/Adobe After Effects [old version]/Scripts/ (and Scripts/ScriptUI Panels/). Copy .jsx/.jsxbin files into the matching 24.6.1 locations.
4. Plug-ins — I’d recommend to reinstall these from an installer if possible, rather than copy them over. A lot changes under the hood over 4 years, so it would also be a good idea to check if there are any updated versions from the developer so you get compatibility fixes too. Only copy raw files as a last resort for plug-ins no longer being distributed.
One more thing worth considering: rather than only installing 24.6.1, you could also install the latest version (26.3) alongside it. It's got a lot of stability fixes and workflow improvements over 24.x that will make your day-to-day work faster, and installing them side-by-side won't disturb whatever anything with 24 — so you can migrate once and try both before deciding which to use.
