Unity 4.0 Painful Upgrade!

Unity Engine
1

Hello,

I am just curious how many other users here are experiencing many issues due to the Upgrade to Unity 4.0

I Upgraded my Version from 3.5.6 and my entire Game Project is Now Broken!

I am not even going to go into the details of what does not work, it’s not worth the time or effort trying to figure it out!

I will downgrade back to 3.5.6 and Complete my Game Project there, and start a New Game Project when i’m Ready to do so in Unity 4.0

This Upgrade is Painful! any one else having similar issues and need to downgrade back to 3.5.6 to get your Project Working Again?

Well that’s why you always have to backup your projects because there is always a risk involved in upgrading.

Yes, ofcoarse I did backup my data! I’m just sharing what Unity 4.0 did to my Project! totally destroyed it!

So that’s why I just downgraded back to 3.5.6, and curious how many others were affected.

My personal Opinion is this is really a Horrible Upgrade! I mean sure there may be lots of new features and so forth but damn! You would think Upgrading would be a little more smoother than this… apartly not with Unity

Well unless you tell us what broke it doesn’t really mean a lot to us. Are you referring to the breaking changes which we’ve been made clearly aware of, or are you referring to other things?

But also, never assume that an upgrade will go smoothly. This is why you’ll find that businesses often stick with “old” software - once a project has started they stick with the same major version they started with, so that significant changes in major updates don’t introduce subtle (or not) errors.

Please let us know what errors you got when importing into 4.0, this will help us improve the upgrade process.

This is why I wait until for a stable version and the majority of the community to upgrade before I do otherwise I back it up.

Only stuff I had that was important enough to worry about when I upgraded was some scripts.
Haven’t been into this all that long so there wasn’t so much to worry about.

Results are varying, most of the time conversion is completely fine, other times there is some tweaking to be done. But when people speak of it breaking horribly, it would be handy to know the details.

sorry for late reply… yes i guess the details will be helpful rather than ranting about how bad my upgrade experience was…

currently there is just too many things going wrong that I do not have the time to document it all and talk about it on here, as time is money as we know… and i need to get my project completed by just downgrading rather than wasting time on tweaking and patching things up…

If or when I have free time I will try to do the community a service and try to log all those bugs, breaks, etc…

I just felt to express myself here, and curious to see how many others were having a tough time with the upgrade as well.

10

Well then I guess we can’t improve for next time.

I’m also moving back to Unity3.5 I was on 4 but too many issues :frowning:

Mainly due to Building for A.R ( Vuforia does not recognise Unity4 )

So I am now trying to go back to 4 but Wow what a head ache ! Now I can’t run 3.5 anymore. Fatal Error issues.

What is the procedure to roll back a version ?

Are there documented instructions on how to do this in Unity ?

Did you upgrade with the release version? I upgraded one of my projects with the first public beta, and it was terrible - all the prefabs were broken, and models that I had moved in the folder structure had their references lost, etc. I re-upgraded (from my backup) after general release, and it worked flawlessly with the new version.
