If you have both license, I prefer not uninstall 13, since 14 has many issues reported.
But if you "upgraded the license", you don't have 13 license any more. you should uninstall it.
Thank you for your post.
There is nothing that requires you to uninstall FileMaker Pro 13 from the machine that is also running your upgrade FileMaker Pro 14 Advanced. I find it handy to have multiple versions of FileMaker installed for testing. If you will only be using FileMaker Pro 14 going forward, then you might uninstall just so it's off the system. This situation is completely up to your preference.
I hope this information is of use!
Many of us who are full-time developers and have multiple clients will keep older versions (I have 11, 12, 13, and 14 currently installed) for backward compatibility. Because some features become deprecated over time, and because if a client still is working with an old version, it's dangerous to assume you can always work in the latest version.
However, if you're a business with a distributed installation, it's often best to move the entire organization to a new version simultaneously, and for the opposite-side-of-the-same-coin reason. If you have some people in your organization working with, say, version 13, and others still using version 11, then whatever the folks using version 13 do won't be accessible by the version 11 folks. So it's better to have everyone on the same version, in this case.
Short answer: It depends.
Mine are in the other direction, but yeah - that's the ticket.
Thank you, that is what I was thinking but was not certain. I appreciate your feedback! :-)
Thanks, I'm currently only teaching myself the platform so it's just me. However, you've given me some food for thought in the future.
