So let’s say I start a project in the free version of Unity 5. After working on the game, I decide that I want to have a customized splash screen. Or I make $100,000 and need to upgrade. Can I open the project that I’ve been working on in Unity 5 Pro?
I don’t know if it makes any difference, but I’m a solo dev.
Thanks for your time.
The TOS is very clear on most of that, but I’m curious about this portion.
I think it just can’t be a collaboration between pro and free machines.
Unity free and pro are the same app; there are no separate “versions”. It’s a license only.

Thanks for your reply, Eric. I’m just wondering if my game that I make in the Unity 5 free version is tagged or encrypted somehow that would make it unusable if I paid for the Unity 5 Pro license and tried to open it there.
No, especially considering that would be a pretty fantastic way of discouraging people from buying Pro. “Enjoy your upgrade, now you can’t open any of your projects, ha ha!”

What about going the other way? I ask only because I could have sworn that it’s stated somewhere that projects are tagged as to what version of the Editor they’re made in and that it can be used for licensing purposes, or something to that vague kind of effect.
Edit: It’s this section, specifically the underlined bit:
I realise that it’s specifically talking about simultaneous use, so doesn’t impact the answer given above.
Unity tag assets used in the Personal Edition of Unity 5. If that asset is then used in Unity 5 Pro, the project will still show the Personal Edition splash screen. The simultaneous use seems to be considered any possible scenario that involves Personal Edition at any point.
But if you upgrade a licence, then open it in Pro, it should recognise it is the same licence and free those assets. My confidence isn’t too high on how reliable that will be considering the number of new Pro users posting on the forums with issues relating to similar problems.
Well once this is working 100%, that’s the answer for @Train_to_Treblinka . When he upgrades the assets will be his account so they will become pro… or something.
I wonder if this applies to script assets. If it does, can’t you just copy & paste the content between files? 
UT should reconsider how some of this works, because I’m sure there are going to be bugs that plague legitimate users and workarounds for the more technically knowledgeable users.
Unity 5 has been out for 5 months now, and I haven’t heard of anyone having such issues. Is there any reason to believe it will change over time?
How many people have gone from Unity 5 Personal to Pro yet? This is something that happens over time.
A thread updated today relates to a different licensing issue, but the kind of situation is very similar. These threads turn up fairly regularly.
Quite a bit people went from personal to pro :). I’m not exactly sure what point you’re trying to make - if there are any issues we’ll fix them.
I’m pretty sure it doesn’t work this way. The EULA specifically allows for using “third party” content developed in any edition. This covers things brought from the asset store or from a third party contractor.
The tagging is basically so that Unity has some evidence if they ever decide to audit your studio.
That is how Unity Support told me it works. I was asking about the contradiction that says it is allowed, followed by a sentence saying it will be tagged because it is prohibited.
I see what’s going on ( ͡° ͜ʖ ͡°)
The guys at UT are just… “fixing the problems”.
I’ll fix you if you carry on 
Joking aside, I was curious about this topic myself. At work we have a few people working on a project with the free version. No one has a pro version. When the game is closer to being finished, they want to upgrade to pro to publish the game. Right now it’s being done by the interns who don’t officially work there.
I carried UT’s message with me and threatened both NJIT and my work with it.
“Thou shalt not gross an excess of 100,000 USD and continue to use Unity Personal Edition”
Or in my derail accent, “Don’t shoot! I’m on your side!”
That sounds like a pretty sketchy business practice. It might just meet the legalities of the EULA, depending on exact labour laws in your area. It definitely is against the spirit and intent of the EULA.
It’s not a game company and there is no official game department. The game department’s chance to exist hinges on the $1500 investment at the end of development to see a profit. It’s very sketchy All of the stuff I contribute is off hours and mostly helping the interns. If it works out, then I will be moved to full time game dev and we’ll have a few pro licenses. I’d like to do that full time.
